摘要:
为研究6061-T4铝合金方管压弯构件平面内稳定力学性能,建立ANSYS有限元模型,分析初始缺陷幅值和单元划分精度对数值计算稳定承载力的影响,并通过现有试验数据对ANSYS有限元模型加以验证。在此基础上,进一步分析构件长细比和荷载偏心率对构件稳定承载力的影响。将《铝合金结构设计规范》GB50429-2007压弯构件面内稳定计算公式得到的相关曲线与数值计算的相关曲线进行比较,发现规范公式偏保守较多。基于大量参数分析,建议对于强硬化铝合金,GB50429相关公式中修正系数η1改取0.8,将文中建议结果和数值计算结果进行比较,较原公式吻合更好。
Abstract:
To study the mechanical properties of 6061-T4 aluminum alloy beam-column, a finite element model was constructed by the nonlinear finite element analysis (FEA). The effect of the initial imperfection and the element segmentation/meshing (mesh size) accuracy on the stability of the 6061-T4 aluminum alloy beam-column was analysed. The nonlinear finite element model was verified by relevant experimental data. Then the length to slenderness ratio and eccentricity rate were analysed by the FEA. Comparing the N/Ny-M/Mp relation curves of Chinese code with that of the FEA, it can be concluded that the in-plane stability capacity of the Chinese code is rather conservative. When the value of η1 of the Chinese code is 0.8, the results of the revised interaction expression show a good agreement with that of the FEA.
