【摘要】：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。
[Abstract]:ABAQUS has outstanding capability in dynamic elastoplastic analysis of complex high-rise and large span spatial structures, but its pre-processing modeling is complicated and complicated. In order to improve the efficiency of modeling, the object-oriented system development technology is adopted, and Auto CAD is used as the graphic processing platform. Using Object Arx, VS2008 and / or / C language, a model conversion program from SAP2000 to ABAQUS for complex high-rise and large-span spatial structures is developed. The key technologies of model transformation, such as connection unit import, node constraint and binding import, are used to convert two actual large span spatial structures separately, and the model information and modal calculation results before and after transformation are compared. The accuracy of the interface is verified.
