Computer-Aided Design of Earthquake-Resistant Structures

该项目的目标是开发设计程序和相关的计算软件，以实现更接近公认的抗震设计理念的经济结构设计。计算机辅助设计软件将被开发用于结构的概率极限状态设计和分析。同时将努力确定地面运动和结构响应参数，这些参数在统计上与结构损伤具有高置信度。将努力分别处理抗震设计中的不确定性和统计变化。通过对简单k -支撑框架系统的后弹性行为进行合理分析，对支撑框架进行研究，以确定影响梁-柱-支撑构件相互作用的关键因素。因此，应获得抗震设计的比例建议。

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.
