采用SAP 2000软件对沈阳奥体中心游泳馆结构进行抗震计算分析。分析选用单钢结构、单混凝土结构、整体结构3种计算模型,采用振型分解反应谱、弹性时程分析、弹塑性时程分析3种计算方法进行分析,结果表明:单钢结构模型不考虑下部混凝土对钢结构地震作用的放大,偏于不安全;单混凝土模型不考虑钢结构带来的整体结构周期变长的有利影响,偏于保守;在罕遇地震作用下,结构满足相关规范的抗震设防目标。
Using SAP 2000 Software to Calculate the Earthquake Resistance of Swimming Pool in Shenyang Olympic Sports Center. Three kinds of calculation models of single-steel structure, single-concrete structure and overall structure were selected for analysis. Three kinds of calculation methods were used, including vibration mode decomposition reaction spectrum, elastic time history analysis and elasto-plastic time history analysis. The results showed that the single steel structure model did not consider The concrete enlargement of the seismic response of the lower concrete to the steel structure is unsafe. The single concrete model does not consider the favorable influence of the steel structure on the structural change of the whole structure, but is conservative. In the case of rare earthquakes, the structure satisfies the relevant specifications Seismic fortification goals.
