摘要

摘要: 为了探究不锈钢芯板T形墙在承受双向压弯荷载作用下的力学性能。首先,使用ABAQUS建立了12组不同的有限元模型进行对比分析,通过对模型的非线性分析,研究其在各个阶段的受力特征和破坏机理,然后通过变化面板厚度、墙肢高宽比、侧板厚度、芯管厚度以及轴压比和偏心角度等参数,分析这些变量对T形墙压弯承载力的影响,得出面板厚度和轴压比是最主要的影响因素。最后将数值分析结果所得到的M_x、M_y归一化后,拟合出不同轴压比下M_x、M_y的相互作用方程。

Abstract: In order to explore the mechanical properties of T-shaped wall with stainless steel core plate under biaxial bending and compression, first of all, 12 groups of ABAQUS finite element models were designed for comparative analysis, the mechanical characteristics and failure mechanism in earch stage were studied, and then the influence of 6 variables on the flexural bearing capacity of T-shaped wall was analyzed by changing parameters such as the thickness of the panel, the aspect ratio of wall limb, the thickness of side plate, the thickness of the core tube, axial compression ratio and eccentric angle, it was concluded that the panel thickness and axial compression were the most significant factors. Finally, the obtained M_x and M_y were normalized to fit the interaction equations of M_x and M_y under different axial compression ratios.
