通过有限元分析软件ABAQUS对T型内置加劲肋双钢板组合剪力墙试件建立了分析模型,结果证明有限元分析结果与相关试验结果总体上吻合较好;通过参数化分析,分析轴压力、混凝土强度、钢材强度、钢板厚度等不同参数对墙体受力性能的影响;基于平截面假定,通过理论分析,推导了适用于钢管束组合剪力墙正截面压弯承载力计算公式。
The finite element analysis software ABAQUS was used to establish an analysis model for the T-type built-in stiffener double-steel composite shear wall specimen. The results show that the finite element analysis results are generally in good agreement with the relevant test results; through the parametric analysis, the axial pressure is analyzed. The influences of different parameters such as concrete strength, steel strength, and steel plate thickness on the mechanical properties of the wall; Based on the flat section assumption, through theoretical analysis, the calculation formula for the bending resistance of the normal section of the composite shear wall of steel tube bundles was deduced.
