基于MIDAS/GEN探讨不同填充墙对RC框架结构动力反应的影响

Based on the MIDAS/GEN discussing the dynamic response of different filling wall of RC frame structure

在RC框架结构中,目前主要采用的设计方法是按照框架结构进行设计,不考虑填充墙的承载,只是将填充墙的自重当作外荷载施加到计算模型上;抗震计算时,考虑填充墙对框架结构刚度的影响,对框架的自振周期进行折减。这种计算分析方法仅能大致估算填充墙对结构周期的影响,无法考虑不同材料、不同布置等情况下的填充墙对结构影响的差异。本文根据算例基于MIDAS/GEN对不同材料、不同布置的RC框架结构进行动力分析,探讨填充墙对结构动力反应的影响。

In the RC frame structure, the current design method is adopted the frame structure design, do not consider the bearing capacity of fill walls,while fill the dead weight of the wall as a load applied to the calculation model;When we calculate earthquake- resistanfion, considering the stiffness of fill walls and the effects of vibration reduction cycle of the framework. This calculation analysis method can only roughly estimate the influence of fill walls in the structure cycle,can＇t consider different materials, different arrangement of filling the influence of wall structure. This paper based on the MIDAS/GEN discussing the influence of the filling wall in the framework structure about different materials,different arrangement.
