摘要:
采用外加剪力墙的体外加固方法,对一个不满足抗震要求的4层中小学框架结构校舍进行加固.通过对不同加固方案的加固结构进行弹性和弹塑性地震反应分析,研究地震作用下不同加固方案对结构的抗震性能影响.数值分析结果表明:外加剪力墙可使原结构各榀框架所受的地震剪力有较大幅度的降低,剪力墙越宽,降幅越大; 可使各楼层层间位移角趋于均匀,有效控制结构层间变形的集中,防止结构层屈服机制的出现; 框架结构梁柱构件的塑性变形明显推迟,结构塑性铰发展减缓.
Abstract:
An external retrofitting shear wall is adopted to strengthen the middle and primary school 4-storey frame structure which don’t meet the seismic requirement.According to elastic and elasto-plastic seismic response analysis,the seismic behavior of retrofitted frame using various strengthening plan was investigated.The analytical results show that the external retrofitting shear wall reduces obviously the seismic force of retrofitted frame,the width of shear wall is positive correlative to the reduction of seismic force,and the shear wall narrows the difference of drift ratio of each storey.Comparing with the original frame,The development of plastic hinge of retrofitted frame is postponed.
