摘　　要：为了研究装配式陶粒混凝土夹芯复合墙板的抗震性能,本文共建立了4个有限元模型,主要包括普通混凝土夹芯复合墙板、陶粒混凝土夹芯复合墙板、纤维增强陶粒混凝土夹芯复合墙板以及实心陶粒混凝土墙板.通过计算结果与实验结果对比分析,验证了计算模型的正确性.采用ABAQUS模拟求解的分析方法,分别研究了4种墙板的滞回性能、延性、承载及变形能力以及刚度退化等性能.结果表明:夹芯复合墙板表现出相对良好的抗震性能;两侧核心承重部件材料对墙板整体抗震性能影响较大;纤维增强陶粒混凝土表现出较好的延性,整体抗震性能相对较好,具有一定推广价值.另外,发展夹芯节能墙板也符合国家提倡的绿色、节能、保温等发展政策.In order to study the seismic performance of assembled ceramsite concrete sandwich wall panel,four finite element models were established in this paper,including ordinary concrete sandwich panel,ceramsite concrete sandwich composite wall panel,fiber reinforced ceramsite concrete sandwich composite wall panel and solid ceramsite concrete wall panel.Through the comparison and analysis of calculation results and test results,the correctness of the calculation model was verified.Using ABAQUS simulation method,the hysteretic performance,ductility,load-bearing and deformation capacity and stiffness degradation of four kinds of wallboards were studied.The results show that:the sandwich composite wall panel shows relatively good seismic performance;the core load-bearing materials on both sides have a great impact on the overall seismic performance of the wall panel;the fiber reinforced ceramsite concrete shows good ductility,and the overall seismic performance is relatively good,which has a certain promotion value.In addition,the development of sandwich energy-saving wallboard is also in line with the national green,energy-saving,thermal insulation and other development policies.
