Bauphysik Kalender 2015: Schwerpunkt: Simulations- und Berechnungsverfahren (Bauphysik Kalender)
by Nabil A. FouadDie technische Komplexität von Gebäuden hat massiv zuggenommen. Fast alle Bereiche der Gebäudetechnik sind heute zumindest teilweise automatisiert, um z. B. das Raumklima zu optimieren, den Energieverbrauch zu senken, Brand- und Rauchentwicklung frühzeitig zu erkennen und zu unterbinden und im Ganzen eine kostengünstigere Bewirtschaftung zu ermöglichen. Numerische Simulationsverfahren sind daher aus der Gebäudeplanung und im Bestand nicht mehr wegzudenken und werden auf allen Gebieten der Bauphysik eingesetzt. Ihre Anwendung erfordert Hintergrundwissen zu den verwendeten Berechnungsverfahren, um sie wirtschaftlich einzusetzen und Fehler zu vermeiden. Auch die Modellgenauigkeit spielt für die Interpretation von Simulationsergebnissen eine bedeutende Rolle und wird häufig unterschätzt, ihre Verifikation muss nachvollziehbar sein. Außerdem sind aufgrund von Vereinfachungen manche Ergebnisse nur für bestimmte Parameter brauchbar. Nicht zuletzt erfordert die Anwendung und Interpretation von Simulationen auch die Berücksichtigung von eventuellen Ungenauigkeiten der Eingabeparameter. Der Bauphysik-Kalender 2015 gibt wertvolle Praxishinweise zur Softwareanwendung anhand von Beispielen.

Beton-Kalender 2014: Schwerpunkte: Unterirdisches Bauen - Grundbau - Eurocode 7 (Beton-Kalender (VCH) *)
by Herausgegeben Von Konrad Bergmeister Wein Frank Fingerloos Berlin Johann-Dietrich Wörner DarmstadtUnderground construction and foundations are very complex and expensive today, particularly in inner cities. In order to provide a quick overview of the interfaces and the necessary dialogue among qualified engineers in modern design and construction, the entire range of disciplines and specialisations involved are described. The latest types of foundations and construction methods in general building are extensively described. Particular attention is paid to the highly non-linear and complex holistic behavior of the system ground-structure and the interaction between the verification of serviceability of the foundation and the limit state of load-bearing capacity in the structure above. Excavations are required for almost all construction projects, from pipe laying to extensive building projects between existing buildings. The essential calculation methods and construction processes are explained here, updated from EAB 2012.

Stahlbau-Kalender 2014: Eurocode 3 - Grundnorm, Außergewöhnliche Einwirkungen (Stahlbau-Kalender)
by Ulrike KuhlmannThis year, practical application notes for the verification formats and optimal design procedures for Part 1-8 "Joints" are included in addition to the revision of Part 1-1 "General Design Rules". With the introduction of the Eurocodes, there are also design changes for aluminium structures. Since there is no comparable European code, DIN 18807 Parts 3 and 9 remain in official use. As a result of the differing delineation of design rules, detailing and application regulations and construction rules, there were gaps in the regulations, which will now be filled by DIN EN 1090 Parts 4 and 5.

Solar and Heat Pump Systems for Residential Buildings (Solar Heating and Cooling)
by Jean-Christophe HadornThe combination of heat pumps and solar components is a recent development and has great potential for improving the energy efficiency of house and hot water heating systems. As a consequence, it can enhance the energy footprint of a building substantially. This work compares different systems, analyses their performance and illustrates monitoring techniques. It helps the reader to design, simulate and assess solar and heat pump systems. Good examples of built systems are discussed in detail and advice is given on how to design the most efficient system. This book is the first one about this combination of components and presents the state of the art of this technology. It is based on a joint research project of two programmes of the International Energy Agency: the Solar Heating and Cooling Programme (SHC) and the Heat Pump Programme. More than 50 experts from 13 countries have participated in this research.
Design of Joints in Steel and Composite Structures: Eurocode 3: Design of Steel Structures. Part 1-8 Design of Joints. Eurocode 4: Design of Composite Steel and Concrete Structures. Part 1-8 Design of Joints
by Jean-Pierre Jaspart Klaus WeynandThis book details the basic concepts and the design rules included in Eurocode 3 Design of steel structures: Part 1-8 Design of joints Joints in composite construction are also addressed through references to Eurocode 4 Design of composite steel and concrete structures Part 1-1: General rules and rules for buildings. Attention has to be duly paid to the joints when designing a steel or composite structure, in terms of the global safety of the construction, and also in terms of the overall cost, including fabrication, transportation and erection. Therefore, in this book, the design of the joints themselves is widely detailed, and aspects of selection of joint configuration and integration of the joints into the analysis and the design process of the whole construction are also fully covered. Connections using mechanical fasteners, welded connections, simple joints, moment-resisting joints and lattice girder joints are considered. Various joint configurations are treated, including beam-to-column, beam-to-beam, column bases, and beam and column splice configurations, under different loading situations (axial forces, shear forces, bending moments and their combinations). The book also briefly summarises the available knowledge relating to the application of the Eurocode rules to joints under fire, fatigue, earthquake, etc., and also to joints in a structure subjected to exceptional loadings, where the risk of progressive collapse has to be mitigated. Finally, there are some worked examples, plus references to already published examples and to design tools, which will provide practical help to practitioners.
Solution Sets for Net Zero Energy Buildings: Feedback from 30 Buildings Worldwide (Solar Heating and Cooling)
by François GardeNet Zero-Energy Buildings have been the object of numerous studies in recent years as various countries have set this performance level as a long-term goal of their energy policies. This book presents a unique study of 30 NZEBs that have been constructed and have had their performance measured for at least 12 months. The study is based upon an international collaborative research initiated by the International Energy Agency - the Solar Heating and Cooling Programme (SHC). It is the first book to evaluate building strategies in houses, educational buildings and offices that have been demonstrated to work in practice. It examines how the design challenges of climate and building type have been addressed, and to what extent the various design approaches have been successful. This book presents convincing evidence that a careful re-thinking of conventional design norms can achieve a far greater performance benefit than is normally feasible. It identifies `solution sets? that work at the whole building level and at the individual building design challenge level for each climate and building type. In doing so, the book provides guidance as to how to improve the design by learning from these cases. Unusually for a book of this type it has examples of buildings in what are conventionally labeled "hot" and "cold" climates. A simple process is proposed for the reader to commission the analysis of their own climate to assess not only the conventional measure of how hot or cold or humid it is, but also to assess its suitability to support other NZEB technical challenge solutions sets such as Daylight or Natural Ventilation or comfort based climate conditioning.
Modeling, Design, and Optimization of Net-Zero Energy Buildings (Solar Heating and Cooling)
by William O'Brien Andreas AthienitisBuilding energy design is currently going through a period of major changes. One key factor of this is the adoption of net-zero energy as a long term goal for new buildings in most developed countries. To achieve this goal a lot of research is needed to accumulate knowledge and to utilize it in practical applications. In this book, accomplished international experts present advanced modeling techniques as well as in-depth case studies in order to aid designers in optimally using simulation tools for net-zero energy building design. The strategies and technologies discussed in this book are, however, also applicable for the design of energy-plus buildings. This book was facilitated by International Energy Agency's Solar Heating and Cooling (SHC) Programs and the Energy in Buildings and Communities (EBC) Programs through the joint SHC Task 40/EBC Annex 52: Towards Net Zero Energy Solar Buildings R&D collaboration. After presenting the fundamental concepts, design strategies, and technologies required to achieve net-zero energy in buildings, the book discusses different design processes and tools to support the design of net-zero energy buildings (NZEBs). A substantial chapter reports on four diverse NZEBs that have been operating for at least two years. These case studies are extremely high quality because they all have high resolution measured data and the authors were intimately involved in all of them from conception to operating. By comparing the projections made using the respective design tools with the actual performance data, successful (and unsuccessful) design techniques and processes, design and simulation tools, and technologies are identified. Written by both academics and practitioners (building designers) and by North Americans as well as Europeans, this book provides a very broad perspective. It includes a detailed description of design processes and a list of appropriate tools for each design phase, plus methods for parametric analysis and mathematical optimization. It is a guideline for building designers that draws from both the profound theoretical background and the vast practical experience of the authors.

Ultra-High Performance Concrete UHPC: Fundamentals, Design, Examples (Beton-Kalender Series)
by Michael Schmidt Ekkehard Fehling Joost Walraven Torsten Leutbecher Susanne FröhlichSelected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since. Ultra high performance concrete (UHPC) is a milestone in concrete technology and application. It permits the construction of both more slender and more durable concrete structures with a prolonged service life and thus improved sustainability. This book is a comprehensive overview of UHPC - from the principles behind its production and its mechanical properties to design and detailing aspects. The focus is on the material behaviour of steel fibre-reinforced UHPC. Numerical modelling and detailing of the connections with reinforced concrete elements are featured as well. Numerous examples worldwide - bridges, columns, facades and roofs - are the basis for additional explanations about the benefits of UHPC and how it helps to realise several architectural requirements. The authors are extensively involved in the testing, design, construction and monitoring of UHPC structures. What they provide here is therefore a unique synopsis of the state of the art with a view to practical applications.
Recommendations on Piling (EA Pfähle)
by Alan Johnson Deutsche Gesellschaft für Geotechnik e.V. / German Geotechnical SocietyThis handbook provides a complete and detailed overview of piling systems and their application. <P><P>The design and construction of piled foundations is based on Eurocode 7 and DIN 1054 edition 2010 as well as the European construction codes DIN EN 1536 (Bored piles), DIN EN 12699 (Displacement piles) and DIN EN 14199 (Micropiles). These recommendations also deal with - categorisation of piling systems, - actions on piles from structural loading, negative skin friction and side pressure, - pile resistances from static and dynamic pile test loading as well as extensive tables with the pile load-bearing capacity of nearly all piling systems based on values from practical experience, - pile groups, - performance of static and dynamic test loading and integrity tests, - load-bearing behaviour and verifications for piles under cyclical, dynamic and impact actions - quality assurance for construction. An appendix with numerous calculation examples completes the work. As part of the approval procedure for offshore wind energy structures, the Federal Office for Shipping and Hydrography (BSH) demands verifications according to the new Chapter 13 ("Load-bearing behaviour and verifications for piles under cyclical, dynamical and impact actions") of the EA Pfähle (the recommendations of the Piling working group - 2nd edition), which deals with external pile resistance for the foundations of offshore wind energy structures and the types of verifications to be provided under cyclical actions. The publication of the EA-Pfähle recommendations by the Piling working group of the German Society for Geotechnics (DGGT), which works with the same members as the piling standards committee NA 00-05-07, is intended to provide assistance for engineers active in the design, calculation and construction of piled foundations. The recommendations can thus be considered as rules of the technology and as a supplement to the available codes and standards.
Strengthening of Concrete Structures with Adhesively Bonded Reinforcement: Design and Dimensioning of CFRP Laminates and Steel Plates
by Roland Niedermeier Wolfgang Finckh Konrad ZilchDesign and construction in existing contexts is becoming increasingly important, and often the structures - sometimes of historical interest - can be preserved easily and at minimum cost by employing strengthening measures. Existing concrete members can be strengthened by using adhesives to bond additional reinforcing elements onto or into those members. This book explains the design rules, together with their background, and uses examples to illustrate their use, specifically for slabs, beams and columns. Concrete member strengthening measures can take the form of, for example, flexural strengthening with externally bonded (surface-mounted) CFRP strips, CF sheets and steel plates, flexural strengthening with CFRP strips bonded in slits (near-surface-mounted reinforcement), shear strengthening with externally bonded CF sheets and steel plates, and column strengthening with CF sheets as confining reinforcement. The explanations and background information provided are mainly based on the new German guideline "Strengthening of Concrete Members with Adhesively Bonded Reinforcement" by the German Committee for Structural Concrete (DAfStb). This is the first European guideline to regulate this topic in the form of a supplement to the Eurocode. As it is planned to produce a document in a future Eurocode 2, the DAfStb guideline serves as a starting point. The authors are extensively involved in the planning, design, operation and inspection of buildings for preservation and reconstruction, and in the updating of European Technical Approval Guidelines (ETAGs) and design rules. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.
Recommendations on Excavations 3e
by Alan Johnson Deutsche Gesellschaft für Geotechnik e.V. / German Geotechnical SocietyWith the issue of these recommendations, which have the character of a standard, the "Building Excavations" working group of the German Geotechnics Association (DGGT) aims to provide assistance with the design and structural calculation of excavation support works.The introduction of the Eurocodes for building control purposes made necessary a revision of the previous edition of the recommendations to comply with the requirements of DIN EN 1997-1:2009 together with the national annex DIN 1997-1/NA:2010-12 and the supplementary regulations of DIN 1054:2010-12. All recommendations were thoroughly checked, revised where necessary and adapted to new knowledge. Chapter 10 "Building excavations in water" was substantially revised. Due to the progress of development of measurement instruments and the more stringent requirements, Chapter 14 "Instrumentation for the monitoring and supervision of building excavation support works" was formulated completely anew. The recommendations of the working group "Building Excavations" should be of assistance,- to simplify the design and structural calculation of excavation support works,- to harmonise loading assumptions and calculation procedures,- to ensure the structural stability of excavation support works and their individual elements and- to improve the cost-effectiveness of excavation support works.
Der Turm und Brücke: Die neue Kunst des Ingenieurbaus
by David P. BillingtonLong recognised as a classic in the USA, "The Tower and the Bridge" is now at last available in German translation. In his preface to the German edition, Jorg Schlaich writes. "This book is essential reading and a pleasure for the "structural engineering artist", in whose structures the connection between form and force flow is visible and which are distinguished by the ideals of efficiency, cost-effectiveness and elegance." Billington founded with this book structural art as a new, independent art form, which he considers equivalent to architecture. It is no coincidence that the title states the two classic domains of the structural engineer; in this case Billington is referring to two outstanding structures of the epoch, the Eiffel Tower and the Brooklyn Bridge. Billington describes in an easily readable style and in an entertaining manner the ideals, principles and methods of structural art during its historical development through examples of structures from outstanding engineers (e.g. Telford, Maillart, Freyssinet, Menn). With the establishment of structural art as an art form and the explication of its inherent principles, Billington gives the reader well founded arguments for the aesthetic discussion of engineering structures. This also provides a basis for criticism of the new art form; for the criticism of construction that has long been demanded. This timeless book thus has the potential to give a new impulse to the debate about construction culture and particularly the aesthetic aspects of structural engineering in German-speaking countries.
