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.
