Author: Luis A. BEDRIÑANA1 and Taiki SAITO2 | Size: 372 KB | Format:PDF | Quality:Unspecified | Publisher: IISEE, Building Research Institute, Tsukuba, Japan. | pages: 8
A methodology to evaluate quantitatively the seismic risk and the cost-effectiveness of a base isolated building
during its lifetime is presented. The process starts with the hazard analysis and the earthquake ground motion
modeling for the studied area. Series of artificial earthquake ground motions are generated by a stochastic method.
To get the response distribution of the target building, several dynamic nonlinear analyses are carried out by using
the generated artificial motions as input waves. By assuming a structural response distribution, the seismic risk
analysis is performed in terms of three structural parameters such as: interstory drift ratio (IDR), floor acceleration
(FA) and the structural damage index (DI). Finally, the cost-effectiveness of using base isolation system is
examined, by comparing the exceedance probability of repair cost in the target building with and without base
isolation during a given time period.

For structures that receive a large earthquake it is required to apply a good technique which suppresses a danger to the minimum irrespective of existing and establishment. A technique of seismic risk management dealt with the quantitative amount of information is to obtain the anticipative amount of the earthquake damages during access peri
od,and is the support tool to select the higher expense efficiency step to reduce an earthquake damage. In this study,the method of seismic risk management is searched for
using the earthquake proof reliability assessment technique. A seismic lose function is calculated from the earthquake damage factors that are modeled by using fragility curves and event trees. The seismic hazard curve is obtained by Nankai offshore scenario earthquake. The third floor or the eighth floor steel structures on a hard or soft ground in Kochi Prefecture are taken up as SRM(Seismic Risk Management Method) study cases. Using structures from as three kinds of seismic code,costs of both initial construction and life cycle are calculated. As the results,the seismic risk reduces to half by ground conditions. Though initial investment becomes high so that earthquake resi stant construction goes up,the life cycle costs and the seismic risk become small. The seismic risk of the base isolation structure is set to zero,and excels as the earthquake resistant construction. Then,the eighth floor steel structure with the base isolation system is applied to obtain time history responses in comparison of those by the different input wave motions. The base isolation building is able to reduce a strong motion because of the long time period shake,and is efective to the short period large earthquake motion

The service-life performance of concrete bridge decks, including maintenance, repair, and rehabilitation needs, is directly related to the care exercised from the preconstruction through post-construction period. This guide provides recommendations for bridge deck construction based on considerations of durability, concrete materials, reinforcement, placing, finishing and curing, and overlays.

Author: David A. Fanella & others | Size: 13 MB | Format:PDF | Quality:Unspecified | Publisher: Springer US | Year: 2nd Ed. 2012 Softcover reprint of the original 1st ed. 1992 | pages: 532 | ISBN: 1461597315 , 978-1461597315
Updating its highly successful predecessor, this new edition incorporates all of the American Institute of Steel Construction's 1989 specifications. Specific AISC section numbers are cited throughout for easy referencing. Sections on highway bridge design and fatigue design, as well as many new practical examples, are among the new features in the Second Edition. Current code provisions are supplemented by new practical examples and numerous AISC design aids are presented. New equiations are also referenced wherever appplicable. With no other books currently addressing the latest edition of the AISC code this guide will find an eager audience among structural engineers, architects, and other professionals.
