［摘要］基于有限元软件ABAQUS，通过选择和开发准确的材料本构关系、选择合适的单元类型、设定合适的阻尼及自动导入模型信息，建立了用于分析光谷国际网球中心15 000座主场馆在罕遇地震作用下性能的有限元模型，并计算分析了结构在6种罕遇地震工况下的响应。结果表明，主场馆的初步设计方案能满足罕遇地震作用下的性能要求。最后，根据结构在罕遇地震作用下的损伤情况，给出了相应的结构调整和局部加强的建议，进一步提高了结构的抗震性能。

Abstract:Based on the finite-element software ABAQUS, a finite element model of the 15 000-seat tennis stadium of Wuhan Optical Valley International Tennis Center was established to analyze the seismic performance under the rare earthquake. To set up the model, accurate material constitutive models were chosen and developed, appropriate element types were selected, appropriate damping was set and model information was automatically imported. Structural responses were calculated and analyzed under six rare earthquake  cases. The results demonstrate that the preliminary design scheme of the stadium structure can satisfy the performance requirements under the rare earthquake. According to the damage conditions of the structure under the rare earthquake, corresponding suggestions such as structural layout adjustment and locally reinforcement were made to improve the seismic performance in advance.

Keywords:Wuhan Optical Valley International Tennis Center; main stadium; ABAQUS; constitutive model; dynamic elastic-plastic analysis
