【摘要】 利用ANSYS软件动力分析功能中的模态分析和谱分析功能对火电厂空冷岛钢结构平台的三维模型进行地震波作用下的抗震分析。通过分析可以看出,空冷岛钢结构平台的地震响应较为明显,同时,找到了空冷岛钢结构平台抗震的薄弱环节,并对薄弱环节进行加固,加固后再次进行抗震分析。由2次得出的结果进行比较得出一些结论。更多还原

【Abstract】 Using modal and spectral analysis in ANSYS’ dynamic analysis, earthquake resistance analysis has been performed on 3D model of steel platform of air-cooling island in thermal power plant. Results show that the earthquake response of the platform is significant, which means that there exist weak links in the platform’s earthquake resistance. Having identified and strengthened the weak links, same analysis is performed again on the new model. Conclusions are made by comparing results from both analysis.更多还原
