填充墙对空间框架非线性地震反应特征的影响
|
摘要
填充墙对钢筋混凝土框架结构的震害有明显影响,已有研究侧重于分析填充墙竖向不规则布置对结构的不利影响。在规则、对称钢筋混凝土典型空间框架的基础上,设计了8种包括平面、竖向不规则在内的填充墙布置方式。在OpenSees平台上,采用基于柔度法的纤维模型模拟柱的双偏压非线性特征,采用等效对角斜支撑压杆模拟填充墙,对各空间框架进行了罕遇地震下的非线性反应分析。结果表明,布置方式合理的填充墙可以有效减小空间框架的地震反应;填充墙沿竖向不规则布置将明显加大框架的地震反应,并容易在填充墙减少或取消的楼层形成"层侧移"反应特征;各楼层具有相同的填充墙平面不规则布置方式,能在一定程度上减小框架的地震反应,但会引起塑性变形在未布置填充墙的局部平面位置集中;填充墙平面、竖向布置均不规则,仍将导致塑性变形集在局部楼层集中,由填充墙竖向不规则所导致的塑性变形集中效应会明显超过平面不规则布置对框架非线性地震反应的不利影响。
Based on the regular and symmetrical reinforced concrete typical spatial frame,8 kinds of infill walls arrangements were selected out for comparison including plane and/or vertical irregular configuration.Based on the OpenSees framework,flexibility method based fiber model was adopted to simulate the nonlinear responses of columns under biaxial bending and varying axial forces,and equivalent model with diagonal compression strut was adopted to simulate the infill walls.Nonlinear responses analyses of the each spatial frame under rare earthquake excitations were carried out.The results showed that reasonable arrangements of infill walls could effectively decrease seismic responses of spatial frames.Vertical irregular configuration of infill walls will significantly increase the seismic response of frames,and story side-sway mechanism always develops at the floor that infill walls were lessened or abolished.Plane irregular configuration of infill walls occurring similarly at every floor could decreases the seismic responses of frame to a certain extent,but plastic deformations will concentrate on some local plane locations where the infill walls were abolished.Plane and vertical irregular configuration of infill walls will also result in the plastic deformations concentrating on specific floor,the effects of concentration of plastic deformations caused by vertical irregular configuration will remarkably surpass the adverse effect of nonlinear seismic responses due to plane irregular configuration of infill walls.
