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 has outstanding capabilities in dynamic elasto-plastic analysis of complex high-rise and long-span space structures, but its pre-processing modeling is cumbersome and complex. In contrast, SAP2000 is an engineering software that mainly faces the structural field, and its integrated preprocessing function is more powerful. It is particularly widely used in the analysis of large-span spatial structures. In order to improve the modeling efficiency, the object-oriented system development technology is adopted, and Auto CAD is used as the graphics processing platform. The Object Arx, VS2008 and /C++ languages are used to develop a high-level and large-span spatial structure model from SAP2000 to ABAQUS. The key technologies of model conversion such as element selection, SD cross-section import, connection unit import, node constraint and constraint import are elaborated. Using the interface to transform the two actual large-span spatial structure projects, and compare the model information and modal calculation results before and after the conversion, and verify the accuracy of the interface.
