框架阻尼填充墙减震效果分析
|
摘要
介绍框架阻尼填充墙的构造、原理与特点。结合某工程,利用PERFORM-3D软件对阻尼填充墙框架、普通填充墙框架和纯框架结构进行了动力特性及弹塑性地震响应分析,研究了阻尼填充墙和普通填充墙对多层框架结构抗震性能的影响及阻尼填充墙的减震效果。结果表明:阻尼填充墙可耗散输入结构的部分地震能量,减小结构构件的非线性耗能,减轻结构构件在地震中的损伤;阻尼填充墙的刚度效应明显小于普通填充墙,对于解决结构纵、横向填充墙布置形式或数量差异过大造成的结构两个平面主轴动力特性不相近的抗震问题具有良好的效果;阻尼填充墙框架结构的自振周期介于纯框架结构和普通填充墙框架结构之间,较普通填充墙框架结构大为延长;采用阻尼填充墙可有效避免普通填充墙对结构破坏机制的不利影响,有助于框架结构实现"强柱弱梁"的屈服机制。
The construction methods,principles and features of damped infill wall(DIW) were presented.Combining with an engineering project,PERFORM-3D software was applied in dynamic characteristics analysis and elasto-plastic seismic response analysis on different frame structures including damped infill wall frame(DIWF),conventional infill wall frame(CIWF) and bare frame(BF).The influences of damped infill wall and conventional infill wall on seismic performance of multi-layer frame structure were studied,and seismic reduction effect of DIWF was studied.The results show that DIW can dissipate partial earthquake energy input of the structure and reduce nonlinear energy dissipation of structural members as well as its damage.The stiffness effect of DIW is much weaker than that of CIW.DIW plays a good role in solving the problem that structural dynamic characteristics of its two principal plane axis are not close due to great difference at the layout form or number of infill wall between longitudinal and transverse.The natural vibration period of the DIWF,which is between that of BF and CIWF,greatly extends compare with CIWF.Using DIW in frame structure can effectively avoid the adverse effects on failure mode of structure caused by infill wall,which contributes to realize the yielding mechanism of"strong column and weak beam".
