Reliability Evaluation of Current Design Procedures for Steel Buildings Under Seismic Loads

该项目侧重于根据现行美国规范设计的建筑系统的可靠性评估。从最近的分析和实验室调查以及从实际地震中建筑物性能的经验中获得的知识将成为本研究的基础。特别注意在负荷和系统建模中遇到的影响不确定性的量化。中低层建筑的性能和安全评价将受到重视。这项研究将导致基于可靠性的一致性设计方法的发展，并改进地震或非地震载荷条件下的损伤控制程序。

This project focuses on the reliability evaluation of building systems designed according to the current U.S. specifications. Knowledge obtained from recent analytical and laboratory investigation and from experience on building performance in actual earthquakes will be the basis of this study. Special attention is paid to quantification of the effect uncertainties encountered in loads and system modeling. Performance and safety evaluation of low and medium- rise buildings will be emphasized. The research will lead to development of consistent reliability-based design methodology and to improved procedures for damage controls under seismic or nonseismic loading conditions.
