摘　　要：复杂高层结构通常都需要进行弹性和弹塑性等计算分析,一般需要两个或者两个以上商业软件进行对比分析计算。但不同软件间缺乏相应的模型转换接口,使用不同软件计算分析时,存在重复建模的难题。为节省建模时间,提高工作效率,通过分析SAP2000和ABAQUS软件之间内在模型数据的转换逻辑,编制MTR1.0程序来完成模型数据的自动转换。编制过程中,通过数学建模方法解决了杆件截面方向定位的难点。同时在上海中心大厦的实际工程中应用,证明了编制的MTR1.0程序具有可行性和高效性,对以后的工程应用有一定的借鉴意义。Complex high-rise structures generally require elastic and elastic-plastic analysis.It normally takes two or more commercial software for analysis and comparison.But for the lack of different software corresponding model transformation interfaces,there is problem of modeling repetition when using different software to calculate and analyze.In order to save modeling time and improve the work efficiency,through analyzing the internal logic of SAP2000 to ABAQUS model data conversion,the model data was transformed from SAP2000 to ABAQUS automatically by MTR1.0 program.In program process,the difficulty of bar cross-section orientation was solved by the mathematical modeling methods.At the same time,through practical engineering application of Shanghai Tower,it has been proved that MTR1.0 program is feasible and efficient,and it could provide references for future engineering applications.
