摘要:
采用通用有限元分析软件ANSYS建立了典型砌体结构教学楼（预制多孔板装配式楼盖）的数值模型。利用有限元时程分析方法，分析房屋在汶川地震波作用下的地震响应，验证了预制多孔板楼盖水平刚度不足是砌体结构教学楼倒塌的主要原因。在此基础上，提出了一种新式加固方法——板底粘贴桁架型钢板条来增强楼盖的水平刚度。采用时程分析方法，对未加固模型与加固后模型的地震响应进行了对比。结果表明：板底粘贴桁架型钢板条法对提高房屋结构抗震防倒塌能力是行之有效的。
Abstract:
Authors used general finite element analysis software ANSYS to build a numerical model of typical masonry teaching building with precast reinforced concrete (RC) slabs. The finite element time history analysis method was used to get this model’s seismic response under Wenchuan seismic wave, proving that inadequate floor’s in-plane stiffness was the key defect causing collapse of masonry teaching building. Based on this analysis, authors proposed a new strengthening method of sticking steel strips under slabs to enhance the floor’s in-plane stiffness. The time history analysis method was used to make comparisons between the seismic responses of unstrengthened and strengthened models. The results show that the strengthening method of sticking steel strips under slabs is effective for anti-seismic collapse of building structures.
