The objective of this project is to develop design procedures and associated computing software to achieve economical structural designs which are closer to the accepted seismic design philosophy. Computer-aided-design software will be developed for the probabilistic limit states design and analysis of structures. A concurrent effort will be made to identify ground motion and structural response parameters which are statistically correlated to structural damage with high confidence. An effort will be made to separately deal with uncertainties and statistical variations in earthquake resistant design. The braced frame will be studied for identification of key factors affecting beam-column-brace member interaction by carrying out rational analyses for the post-elastic behavior of simple K-braced frame systems. Thus, proportioning recommendations for seismic design should be obtained.

该项目的目标是制定设计程序， 相关计算软件以实现经济的结构设计 更接近公认的抗震设计理念。 计算机辅助设计软件将被开发用于概率 结构极限状态设计与分析。 同时进行的努力 将确定地面运动和结构反应 与结构损伤统计相关的参数， 高信心。 将努力分别处理 抗震设计中的不确定性和统计变异 设计 将研究支撑框架的关键识别 影响梁柱-支撑构件相互作用的因素， 简支K型支撑后弹性性能的合理分析 框架系统 因此，抗震设计的比例建议 应该获得。
