Author: Demin Feng , Tian-Chyuan Chan , and Shuguang Wang , Hsi-Yun Chen and Yaw-Nan Chang | Size: 424 KB | Format:PDF | Quality:Unspecified | Publisher: 4th International Conference on Earthquake Engineering Taipei, Taiwan October 12-13, 2006 | Year: 2006 | pages: 09
The procedures to do response analysis of a seismically isolated building are summarized based on the building codes of Japan, China, the USA, Italy and Taiwan. While a dynamic response analysis method is recommended in all five building codes, a simplified design procedure based on equivalent linear analysis is also permitted under limited conditions. Subsequently, a typical 14-story reinforced concrete building, isolated with lead-rubber bearings is analyzed using each of the five building codes. The average response values are taken as design values to compare with the results by the equivalent linear analysis method. The deformation of the isolation level and the base shear force coefficient of the superstructure are compared. Finally, the response reduction factor defined in the Japanese code is applied to the other four building codes to improve the accuracy of equivalent linear analysis results.

Despite all the efforts being put into expanding renewable energy sources, large–scale power stations will be essential as part of a reliable energy supply strategy for a longer period. Given that they are low on CO2 emissions, many countries are moving into or expanding nuclear energy to cover their baseload supply. Building structures required for nuclear installations whose protective function means they are classified as safety–related, have to meet particular construction requirements more stringent than those involved in conventional construction. This book gives a comprehensive overview from approval aspects given by nuclear and construction law, with special attention to the interface between plant and construction engineering, to a building structure classification. All life cycle phases are considered, with the primary focus on execution. Accidental actions on structures, the safety concept and design and fastening systems are exposed to a particular treatment. Selected chapters of the German concrete yearbook "Beton–Kalender" are now available in English. The new English BetonKalender Series delivers internationally useful engineering expertise and industrial know–how from Germany. The Beton–Kalender was founded in 1906 in Berlin, and very soon after it has become a "bible" for construction engineers. Its founder Fritz von Emperger (1862–1942) thought that it should support the annual progress of the new building method with ferro–concrete structures "until its tempestuous development would be brought to the end". But, with exception 1945–50 it is published annually until today.

Increasing vibration problems encountered in the last few years show that footbridges should no longer be designed for static loads only but also for the dynamic actions and vibration behaviour of the footbridge due to pedestrian loading.
For this reason European research has been performed to come up with a design concept for footbridges that takes into account different traffic situations and individual demands on vibration comfort. So the elaborated guideline considers different types of pedestrian traffic and the traffic density which can greatly influence comfort requirements of the bridge and the dynamic behaviour. It is important to predict the effect of pedestrian traffic on footbridges at the design stage and in the later verification of serviceability in order to guarantee a comfort level for the user. This guide gives recommendations for designer and client to find relevant design situations as well as methods how to prove if vibration requirements are fulfilled

A Beginner's Guide to Structural Equation Modeling 3rd ed
Author: Randall E. Schumacker & Richard G. Lomax | Size: 7.8 MB | Format:PDF | Quality:Unspecified | Publisher: Routledge | Year: 2010 | pages: 531 | ISBN: 1841698911
This best-seller introduces readers to structural equation modeling (SEM) so they can conduct their own analysis and critique related research. Noted for its accessible, applied approach, chapters cover basic concepts and practices and computer input/output from the free student version of Lisrel 8.8 in the examples.
Each chapter features an outline, key concepts, a summary, numerous examples from a variety of disciplines, tables, and figures, including path diagrams, to assist with conceptual understanding.
The book first reviews the basics of SEM, data entry/editing, and correlation. Next the authors highlight the basic steps of SEM: model specification, identification, estimation, testing, and modification, followed by issues related to model fit and power and sample size. Chapters 6 through 10 follow the steps of modeling using regression, path, confirmatory factor, and structural equation models. Next readers find a chapter on reporting SEM research including a checklist to guide decision-making, followed by one on model validation. Chapters 13 through 16 provide examples of various SEM model applications. The book concludes with the matrix approach to SEM using examples from previous chapters.

The advantages of composite materials include a high specific strength and stiffness, formability, and a comparative resistance to fatigue cracking and corrosion. However, not forsaking these advantages, composite materials are prone to a wide range of defects and damage that can significantly reduce the residual strength and stiffness of a structure or result in unfavorable load paths.
Emphasizing defect identification and restitution, Defects and Damage in Composite Materials and Structures explains how defects and damage in composite materials and structures impact composite component performance. Providing ready access to an extensive, descriptive list of defects and damage types, this must-have reference:
• Examines defect criticality in composite structures
• Recommends repair actions to restore structural integrity
• Discusses failure modes and mechanisms of composites due to defects
• Reviews NDI processes for finding and identifying defects in composite materials
Relating defect detection methods to defect type, the author merges his experience in the field of in-service activities for composite airframe maintenance and repair with indispensable reports and articles on defects and damage in advanced composite materials from the last 50 years.
