Reliability Bases for Seismic Safety Evaluation and Struc- tural Rehabilitation

该项目继续发展基于可靠性的概念和方法来评估结构的地震安全性。根据结构的损伤容限和抗倒塌可靠性，建立了结构损伤模型。从最近的地震中获得的破坏数据将被用于校准这些模型。将对新系统和现有系统进行损坏分析。研究结果将纳入修复现有建筑物的标准或准则。损伤模型将从钢筋混凝土建筑扩展到包括平板建筑和钢结构的损伤，结合了国内外已有的现场和试验数据。此外，还将定义与破坏相关的地面运动强度测量，以反映地震的真实破坏潜力。本研究将继续发展损伤限值设计理念和方法的基本基础。

This project continues the development of reliability-based concepts and methods for assessing the seismic safety of structures. Structural damage models are developed in terms of damage tolerance and reliability against collapse. Damage data obtained from recent earthquakes will be used to calibrate these models. Damage analysis of new and existing systems will be conducted. The results will be incorporated into the criteria or guidelines for the rehabilitation of existing structures. The damage models will be extended from reinforced concrete buildings to include damage of flat slab buildings and steel structures, incorporating field and experimental data existing worldwide. In addition, a damage-related ground motion intensity measure will be defined to reflect the real damage potential of an earthquake. The stucy will continue to develop the fundamental basis of damage limiting design concept and methodolgy.
