基于IDA的群体典型框架结构的震害预测研究
|
摘要
为了更好地服务于城市抗震防灾规划,研究典型钢筋混凝土(RC)框架结构建筑群体震害矩阵,形成初步适用于群体震害预测的方法。建立设防烈度分别为6,7,8度的3层典型框架结构和设防烈度为7度下的3,6,9层的典型框架结构模型,然后在动力增量时程分析(IDA)方法的基础上,分析各框架结构在不同地震作用下的破坏规律。最终得到各框架结构在地震作用下的易损性曲线和震害矩阵。结果表明,各破坏状态下的易损性曲线符合对数正态函数分布;典型框架结构随着抗震设防烈度的提高,抗地震破坏能力增加;随着层数的增加,抗地震破坏能力减弱。
In order to serve the urban earthquake disaster prevention plan much better,an earthquake damage natrix of a typical RC frame structure group was studied,and a preliminary method for predicting group seismic damage was worked out.Models of 3 layers typical frame structures with 6,7,8 fortification intensity and 3,6,9 layers typical frame structures with 7 fortification intensity were made and analyzed based on IDA method.vulnerability curves and earthquake damage matrix of each frame structure under seismic condition were obtained.The results show that the vulnerability curves conform to logarithmic normal distribution function,that with the improvement of seismic fortification intensity,earthquake resistance of typical frame structure increases,that with,and that an increase in the layer number lowers the earthquake resistance.
