SAP2000到ABAQUS的模型转换程序研究与开发

Study and development of the model converting program from SAP2000 to ABAQUS

ABAQUS在复杂高层和大跨度空间结构动力弹塑性分析方面能力突出,但其前处理建模繁琐复杂;相比之下,SAP2000作为主要面向结构领域的工程软件,其集成化的前处理功能更加强大,在大跨度空间结构分析中应用尤其广泛。为提高建模效率,采用面向对象的系统开发技术,以Auto CAD作为图形处理平台,利用Object Arx及VS2008和/C++语言开发了复杂高层和大跨度空间结构从SAP2000到ABAQUS的模型转换程序。详细阐述了单元选取、SD截面导入、连接单元导入和节点约束和束缚导入等模型转换的关键技术。运用接口对两个实际大跨度空间结构工程分别转换,对比转换前后的模型信息和模态计算结果,验证了接口的准确性。

ABAQUS is competent in dynamic elasto-plastic analysis of complex high-rise and large-span spatial structure,but its preprocessing is tedious and complex. By contrast,SAP2000,as a engineering software,is more integrated in preprocessing function and especially widely used in the analysis of the large-span spatial structure. Based on the object-oriented technique and the graphics processing platform of Auto CAD,a model converting program was developed to transform the complex high-rise and large-span spatial structural model from SAP2000 to ABAQUS by using Object Arx and Visual C + + programming language,which greatly increased the efficiency of ABAQUS preprocessing. The import of SD-Section,link element,joint restraint and constraint,the choice of element were elaborated in details. Finally,two real large-span spatial structures were used to test the accuracy of the converting software by comparing the model information and modal calculation results before and after conversion.
