摘要]本文开发并实现了将有限元模型由SAP2000软件导入MSC.MARC软件中的接口程序SAP2MARCMSC.MARC软件的可视化后处理程序MARCPOST。采用MSC.MARC子程序和UMAT程序所生成的材料数据,对某200m结构进行了大震作用下考虑应变率效应的动力弹塑性计算,并结合MARCPOST程序对结果进行提取和分析,可转换多种结构单元。

Abstract: An interface program named SAP2MARC for converting from commercial software SAP2000 into software MSC.MARC and a visual post-processing program named MARCPOST for software MSC.MARC were developed. At last, the developed MSC.MARC subroutine and  material data generated by the program UMAT were used to conduct seismic elastic-plastic analysis for an tall building with 200m high under the rare earthquake considering the effect of strain-rate, and the MARCPOST was used to analyze computation results which can transform several types of elements.
