摘 要:通过对4片新型EPS模块浇筑墙体进行轴心和偏心受压试验,研究了试件的破坏形态、极限承载力和变形规律。在试验基础上,利用ABAQUS软件建立了新型EPS模块浇筑墙体有限元模型,并对试件的极限承载力进行了对比分析。结果表明:新型EPS模块内存在连接桥,墙体的破坏首先出现在连接桥处,最终破坏形式为受压区混凝土破坏;随着偏心距逐渐增大,墙体的极限承载力明显降低,应变与普通混凝土墙体的变化相似;有限元分析结果与试验结果吻合良好,可为工程设计提供分析方法和理论依据。
Abstract: Four new EPS module cast-in-place walls were tested under axial compression and eccentric compression, and the failure mode, ultimate bearing capacity and deformation law of the specimens were studied. On the basis of the test, the finite element model of new EPS cast-in-place wall was established by using ABAQUS software, and the ultimate bearing capacity of the specimen was compared and analyzed. The results show that there is a connecting bridge in the new EPS module, and the wall failure first appears at the connecting bridge, and the final failure mode is concrete failure in the compression zone. With the increase of the eccentricity, the ultimate bearing capacity of the wall decreases obviously, and the change of the concrete strain is similar to that of the ordinary concrete wall. The results of finite element analysis are in good agreement with the test results, which can provide analysis method and theoretical basis for engineering design.
