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。
After the Pishan earthquake, the infill walls of the frame structure cracked seriously and the damage was obvious. The characteristics and causes of earthquake damage were analyzed. Comparing the seismic capacity of filled walls with different masonry materials, mortar grades and structural columns, the infilled walls embedded in a single frame were taken as examples. Under the action of Pishan earthquake, the internal force produced by interlayer displacement in the filled wall exceeds the shear capacity of the wall itself. Based on this, combined with the actual seismic damage of the Pishan earthquake, The design proposal, provides the reference for the frame structure design in the future.
