再生混凝土组合砌体非线性有限元分析

Nonlinear finite element analysis of combined masonry using recycled concrete

为研究再生混凝土组合砌体这一新型结构的抗震性能,在水平低周反复荷载试验基础上,利用ANSYS有限元分析软件建立再生混凝土组合砌体的有限元计算模型,并进行低周反复荷载下抗震性能有限元分析。分析结果表明:与普通砖砌墙体相比,再生混凝土组合砌体的抗震性能明显提高,且随着再生混凝土墙体比例的增加,再生混凝土组合砌体的抗震性能随之增加。并且分析结果还验证了ANSYS有限元分析软件对再生混凝土组合砌体分析的可行性。

For the study on seismic performance of combined masonry using recycled concrete, which is a new structure, based on the test under horizontal low-cyclic loading, we utilized ANSYS finite element analysis software to establish a finite element calculation model of combined masonry using recycled concrete, and conducted finite element analysis of seismic performance under horizontal low - cyclic loading. The analytical results show that comparing with ordinary brick wall, the seismic performance of combined masonry improved obviously, and with the increasing of proportion of recycled concrete, the seismic performance of combined masonry improved as well. And the analytical results also verify that it is feasible to use ANSYS finite element analysis software to analyze combined inasonly.
