| 摘 要： | 针对密肋复合墙的构造特点及在地震作用下"砌块-框格-外框"的破坏顺序,提出利用加气混凝土砌块置换墙体中破坏的砌块以恢复和提高受损密肋复合墙结构抗震性能的加固方法.对加固后的密肋复合墙进行了低周反复荷载试验,分析了墙体破坏过程和钢筋应变状况,重点研究了加固后复合墙的滞回曲线特点及承载力、刚度、延性等抗震性能,并与空框格框...

| Abstract: | Based on the construction feature and block-frame-outer frame failure characteristics of the multi-ribbed composite wall,the strengthen method for damaged multi-ribbed composite wall with aerated concrete blocks to recovery and enhance the seismic performance of the structure was proposed.Through cyclic loading tests on strengthen composite wall,the failure process and steel bars strain were analyzed,and the hysteretic curve character and seismic performance such as bearing capacity,stiffness,ductility and ... |
