摘要

增设翼墙方法是提高RC框架结构抗震性能的常用方法。以一个按照现行规范正常设计的7层RC框架结构为例,进行了翼墙加固前后结构的静力弹塑性对比分析和一个缩尺比为1:4的翼墙加固RC框架结构振动台试验。试验及分析结果表明:增设翼墙后显著提高了原结构的抗侧能力,各层层间变形更趋均匀,并有利于“强柱弱梁”屈服机制的实现。宏观破坏模式为翼墙率先发生破坏进行耗能,在极震工况下,翼墙脚部钢筋屈曲而框架柱脚部钢筋尚未达到屈服应变,表明翼墙可有效保护框架柱,实现了多一道抗震防线的作用。

Abstract

Attaching wing walls is a common measure in the seismic retrofit of RC frames. A 7-story RC frame designed in accordance with the conventional design norm was taken as an example to study the seismic behavior of this combined system. Pushover analysis and a 1:4 scale shaking table test were performed. The results show that lateral resistance of the structure was enhanced, distribution of story drifts became more uniform and the realization of "strong column-weak beam" mechanism was facilitated based on the attached wing walls. Damage procedure observed during the tests showed that wing walls first damaged to dissipate the seismic energy. In the extreme shaking, reinforcement in the bottom of wing walls was bucking, while the reinforcement in the bottom of columns have not reached the yielding strain. It proved that wing walls can protect the frame columns and an extra seismic fortification line was achieved.
