［摘要］皮山地震发生后，框架结构的填充墙开裂严重，震害明显。分析了震害的特点和原因，对比计算不同砌体材料、砂浆等级和有无构造柱的填充墙的抗震受剪承载力, 以嵌砌于一榀框架内的填充墙为例，计算分析表明此次皮山地震作用下框架层间位移在填充墙面内产生的内力超过了墙体自身的抗震受剪承载力，基于此并结合皮山地震的实际震害，提出对带填充墙框架结构的设计建议，为今后框架结构设计提供参考。［关键词］框架结构; 填充墙; 震害; 裂缝; 砌体抗震受剪承载力中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2016)08-0044-04
Seismic damage analysis of RC frame structures with infilled walls in Pishan earthquakeHe Ying, Xu Qin(HFUT Institute of Architectural Design, Hefei 230009, China)Abstract: After Pishan earthquake, infilled walls of RC frame structures were cracked seriously with obvious damages. The characteristics and causes of seismic damage were analyzed. Seismic shear bearing capacities were calculated and compared for infilled walls with different masonry materials, different mortar ratings and different setting conditions of structural columns. Taking an infilled wall in a piece of frame structure as an example, through analysis and calculation, it is concluded that the internal forces of the infilled wall due to the frame inter-layer displacement in Pishan earthquake exceed seismic shear bearing capacity of the wall. Based on the study and actual seismic damages in Pishan earthquake, suggestions were made for frame structures with infilled walls, providing references for future design of frame structural design.Keywords: frame structure; infilled wall; seismic damage; crack; seismic shear bearing capacity of brick masonry
