摘 要:为了提高RC(钢筋混凝土)框架结构的抗震性能,利用SAP2000软件分析了无控数值模型和有控数值模型(附加粘滞阻尼器)的动力特性和振动响应,验证了SAP2000模拟粘滞阻尼器减震效果的适用性。对比分析了三种粘滞阻尼器布置方案的结构抗震效果。结果表明:粘滞阻尼器按层间位移角比例进行分配对结构位移的控制效果最佳;采用多目标优化布置方案对结构的位移控制和加速度控制效果明显,结构的安全性能和舒适度提升显著。
Abstract: To enhance the seismic performance of RC structures, the dynamic characteristics and vibration response of uncontrolled numerical models and controlled numerical models (with additional viscous dampers) were analyzed using SAP2000 software, and the applicability of SAP2000 to simulate the damping effect of viscous dampers was verified. Three kinds of damper layout schemes were used to analyze the seismic performance based on displacement. The results show that the distribution of viscous dampers according to the proportion of displacement angle is the best for the displacement control of the structure. The multi-objective optimization layout scheme has obvious displacement control and acceleration control effect on the structure, which significantly improves the safety performance and comfort of the structure.
