Research of Seismic Performance of Recycled Concrete Block Masonry Wall Based on ANSYS Finite Element Simulation

为了定性研究再生混凝土开孔砌体的抗震性能,利用ANSYS软件对再生混凝土砌块砌体墙建立了仿真模型,针对再生混凝土砌块砌体墙在孔洞状况下施加水平低周反复荷载的三种情况、在孔洞状况下存在竖应力状况的两种情况、在孔洞状况下设有芯柱时的一种情况分别进行了仿真计算和分析;并将仿真结果与再生混凝土无孔状况进行了比较,从比较结果来看,模型能够定性分析再生混凝土砌块砌体墙的状态,为进一步利用该模型研究再生混凝土砌块砌体墙的工况提供了指导.

Openings to the qualitative study of recycled concrete masonry seismic performance, by using ANSYS software of recycled concrete block masonry wall, a simulation model is established in the study. In view of the recycled concrete block masonry wall under the hole conditions of three horizontal low cyclic loading conditions, the condition of vertical stresses are presented in a hole condition under the two cases, the condition of the hole of a core column when a situation has been carried out on the simulation calculation and analysis, and the simulation results are compared with those of the recycled concrete with no hole condition, from the point of the simulation results, the model is good for the state of the qualitative analysis of recycled concrete block masonry wall, for the further study of recycled concrete block masonry wall is obtained by using the model of the working condition and providing references on the basis.
