设计13榀不同构筑方案的阻尼填充墙框架(DIW-框架)
采用ANSYS软件
对空框架、传统填充墙框架(CIW-框架)和DIW-框架进行单调静力荷载作用下的响应分析
对比研究CIW和不同构造的DIW的性能。分析结果表明:DIW在框架侧移时
砌体单元平动
侧向变形集中于VEM层;与CIW相比
其受力大为降低
不易破坏;DIW能给框架提供一定的刚度支持
但刚度效应和约束效应较CIW明显削弱
能延长结构周期
提高结构变形能力和延缓结构破坏。墙体划分及VEM层构筑方案对DIW性能的影响有明显的规律性:砌体单元划分数量愈多、VEM层刚度愈小
DIW对框架的支撑和约束就愈弱。工程中
可通过调整VEM层橡胶的硬度和厚度来控制DIW对框架的刚度贡献和约束程度
发挥填充墙提供刚度支持、保证结构正常使用的积极作用
解决因填充墙对框架约束过强造成结构构件破坏等抗震问题。
Thirteen frames filled with damped infill walls(DIW)and possessed of different construcionts were designed.Moreover
behaviors of the above frames
the frame filled with conventional infill wall(CIW)and the bare frame under the monotonic-static load were simulated using software ANSYS.Based on the results
the performances of the CIW and the DIWs were studied.It′s revealed that
the DIW′s masonry element moves horizontally and the wall′s deformation focuses on the VEM layers when the surrounding frame sways.In comparison with CIW
DIW bears much smaller force and is not damaged easily.It can provide certain stiffness to the frame
but produces much weaker stiffness effect and restraint effect than CIW which makes it be able to extend the structure period
enhance the structure deformation ability and delay the structural damage.Furthermore
the influences of the wall division scheme and the VEM layer construction scheme on the DIW performance have distinct regularity.The larger division number of the masonry element and the softer of the VEM layer
the weaker the DIW strut and restraint to the frame.In practical engineering
we can regulate the stiffness contribution of the DIW by adjusting the VEM layers′material hardness or layer thickness so as to give full play of the positive role of the infill wall in providing certain lateral stiffness for the frame to satisfy the normal usage demand
solve the problem of the infill causing structural components′damage for it strutting and restraining the frame too strongly.
