Experiment and Calculation of Reinforced Concrete at Elevated Temperatures


Book Description

Concrete as a construction material goes through both physical and chemical changes under extreme elevated temperatures. As one of the most widely used building materials, it is important that both engineers and architects are able to understand and predict its behavior in under extreme heat conditions. Brief and readable, this book provides the tools and techniques to properly analysis the effects of high temperature of reinforced concrete which will lead to more stable, safer structures. Based on years of the author's research, Reinforced Concrete at Elevated Temperatures four part treatment starts with an unambiguous and thorough exposition of the mechanical behaviors of materials at elevated temperature followed by a discussion of Temperature field of member sections, Mechanical behaviors of members and structures at elevated temperature, ending with Theoretical analysis and practical calculation methods. The book provides unique insight into: - Coupling thermal-mechanical constitutive relation of concrete - Exceptional analyses of beams and columns of rectangular section with three surfaces and two adjacent surfaces exposing to high temperature - Measurement and analysis of redistribution of internal forces of statically indeterminate structure during heating-loading process - Finite element analysis and calculation charts for two-dimensional temperature field of structural members - Finite element analysis and simplified calculation method for reinforced concrete structure at elevated temperature With this book, engineers and architects can effectively analyze the effect of high temperature on concrete and materials which will lead to better designs of fire resistant and damage evaluation and treatment after fire. - Tools and techniques for analyzing the effects of high temperature on concrete and reinforcement materials - Measurement and analysis of redistribution of internal forces of statically indeterminate structure during the heating-loading process - Finite element analysis and calculation charts for two-dimensional temperature field of structural members - Finite element analysis and simplified calculation method for reinforced concrete structure at elevated temperature

The contributions present traditional and new ideas that will open novel research directions and foster multidisciplinary collaboration between different specialists.




Fundamental Research on Creep and Shrinkage of Concrete


Book Description

Today research on creep and shrinkage of concrete is diversified to such a degree that specialists working in different areas sometimes find it difficult to understand one-another. Materials scientists are mainly interested in processes on a microstructural level but they do not necessarily understand the relevance of time dependent deformation in structural design. On the other hand engineers who apply simplified model laws in non-elastic structural analysis are not always in the position to judge the limitations implied in their approach. It is generally realized that further development can be stimulated by a more effective exchange of results and ideas among the different groups involved. In an attempt to bridge this obvious gap in September 1980 there was a Conference organized at Swiss Federal Institute of Technology in Lausanne. The papers presented at this meeting covered the wide range starting with microstructural aspects and mechanisms and including constitutive modelling and structural creep analysis. These contributions together with summaries of two panel discussions are being published in this volume. All serious of the meeting have been introduced by invited lectures. These papers will be published in a special volume "Creep and Moisture Effects in Concrete". This special volume is rather to be a general survey of the different areas covered while the present conference proceedings provide a unique selection of research papers. Nowadays time-dependent deformation of concrete can be taken into consideration realistically by computerized structural analysis.




Experimental Research in Earthquake Engineering


Book Description

In this volume, top seismic experts and researchers from Europe and around the world, including the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) in the USA, present the most recent outcome of their work in experimental testing, as well as the results of the transnational access activities of external researchers who have used Europe's seven largest and most advanced seismic testing facilities in the framework of the Seismic Engineering Research Infrastructures for European Synergies (SERIES) Project financed by the European Commission in its 7th Framework Programme (2007-2013). This includes EU’s largest reaction wall facility, EU's four largest shaking table laboratories and its two major centrifuges. The work presented includes state-of-the-art research towards the seismic design, assessment and retrofitting of structures, as well as the development of innovative research toward new fundamental technologies and techniques promoting efficient and joint use of the research infrastructures. The contents of this volume demonstrate the fruits of the effort of the European Commission in supporting research in earthquake engineering.
