相邻结构在近远场地震作用下的易损性分析
|
摘要
对连接Maxwell模型的两相邻钢筋混凝土框架结构建立二维模型,考虑了梁柱单元及阻尼器单元在大震作用下的非线性行为,通过相邻结构在近场及远场地震作用下的增量动力分析(IDA),研究了Maxwell阻尼器优化参数理论表达式在结构经历初始弹性、屈服直至倒塌全过程的适用性,并基于IDA分析的结果,对未控和控制情况下相邻结构在近、远场地震作用下的易损性曲线进行了比较分析,从性能评估的角度研究了Maxwell阻尼器对相邻结构在不同地震波及不同地震动强度水平下的控制效果。
Two-dimensional models of two adjacent reinforced concrete frames connected with Maxwell dampers were set up which considered the nonlinear behavior of beam-column and damper elements under major earthquakes. Through a lot of incremental dynamic analysis( IDA) under near-field and far-field earthquakes,it investigated the applicability of Maxwell damper tuning parameters theoretical expression when structures experienced the whole process from initial elastic,yield until to final collapse. Based on the results of IDA,comparative analysis of seismic fragility curves of structures under near-field and far-field earthquakes with control and without control has been done. From the perspective of performance evaluation,it studied the control effect of Maxwell damper under different seismic waves and different seismic intensities.
