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.

该项目继续发展基于可靠性的 地震安全性评估的概念和方法 结构. 结构损伤模型是根据 破坏容限和抗倒塌的可靠性。 损害 从最近的地震中获得的数据将用于 校准这些模型。 将对新的和现有的系统进行损坏分析。 结果将纳入标准或 现有结构的修复准则。 损伤模型将从钢筋混凝土扩展到钢筋混凝土 包括平板建筑和钢结构建筑的损坏 结构，结合现有的现场和实验数据， 国际吧 此外，一个与损伤相关的地震动强度测量 将被定义为反映真实的损害潜力， 地震 该研究将继续发展的根本基础， 损伤限制设计的概念和方法。
