［摘要］皮山地震發(fā)生后，框架結(jié)構(gòu)的填充墻開(kāi)裂嚴(yán)重，震害明顯。分析了震害的特點(diǎn)和原因，對(duì)比計(jì)算不同砌體材料、砂漿等級(jí)和有無(wú)構(gòu)造柱的填充墻的抗震受剪承載力, 以嵌砌于一榀框架內(nèi)的填充墻為例，計(jì)算分析表明此次皮山地震作用下框架層間位移在填充墻面內(nèi)產(chǎn)生的內(nèi)力超過(guò)了墻體自身的抗震受剪承載力，基于此并結(jié)合皮山地震的實(shí)際震害，提出對(duì)帶填充墻框架結(jié)構(gòu)的設(shè)計(jì)建議，為今后框架結(jié)構(gòu)設(shè)計(jì)提供參考。［關(guān)鍵詞］框架結(jié)構(gòu); 填充墻; 震害; 裂縫; 砌體抗震受剪承載力中圖分類(lèi)號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
