［摘要］基于有限元軟件ABAQUS，通過選擇和開發(fā)準確的材料本構(gòu)關(guān)系、選擇合適的單元類型、設(shè)定合適的阻尼及自動導(dǎo)入模型信息，建立了用于分析光谷國際網(wǎng)球中心15 000座主場館在罕遇地震作用下性能的有限元模型，并計算分析了結(jié)構(gòu)在6種罕遇地震工況下的響應(yīng)。結(jié)果表明，主場館的初步設(shè)計方案能滿足罕遇地震作用下的性能要求。最后，根據(jù)結(jié)構(gòu)在罕遇地震作用下的損傷情況，給出了相應(yīng)的結(jié)構(gòu)調(diào)整和局部加強的建議，進一步提高了結(jié)構(gòu)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
