摘要
结构体系基于增量动力分析(Incremental Dynamic Analysis,IDA)方法的抗地震倒塌性能评估中,含有大量时程分析,工作极为繁重乏味,迫切需要自动化控制方法。采用软件接口技术用Matlab语言编制主控制程序,利用system命令在高级语言环境中捆绑了ANSYS和LS-DYNA两种软件,能够自动进行前处理、计算和后处理,并能根据上一步的计算结果确定下一步的分析行为,从而能自动地切换地震波、调幅、捕捉倒塌点,由此实现了倒塌分析的完全自动化。
Seismic collapse assessment of structure system based Incremental Dynamic Analysis （IDA） includes thousands of time history analyses, and the work is heavy and tedious, so automated analysis control method is needed. The paper developed a control program by Matlab and software interface technology, which takes advantage of ＇system＇ command to launch ANSYS and LS-DYNA software in turn to finish modeling, solution, and postprocessing work, further more, determining the next operation according to the result of last analysis and beforehand chosen collapse criterion. As a result, the tedious tasks of switching and scaling earthquake waves, capturing collapse point become automated so that collapse assessment based IDA can be easily performed.
