基于某核电厂大跨单侧钢板混凝土(HSC)空心组合屋盖中的一榀模块的缩尺静载试验(1∶3)情况,通过ANSYS软件,建立组合板试件的非线性有限元分析模型。通过对比数值计算与实际试验的荷载-挠度曲线,验证模型的有效性。计算表明,加载过程中板侧腹板下部混凝土表面最先出现微小的裂缝,在适当的连接和锚固情况下,钢板和混凝土能够很好地协同工作,整个构件具有较高的承载力和刚度,同时表现出良好的延性。
Based on the case of a 1: 3 scale shrinkage test of a hollow module roof in a large-span single-sided steel-concrete (HSC) roof of a nuclear power plant, ANSYS software was used to establish nonlinear finite element analysis model. The validity of the model is verified by comparing the numerical calculation with the actual test load-deflection curve. The calculation shows that the cracks on the concrete surface of the lower part of the web at the web side during the loading process are the first to appear tiny cracks, and the steel sheet and the concrete can work well together under appropriate connection and anchoring conditions. The whole component has high bearing capacity and rigidity, At the same time showed good ductility.
