对钢骨混凝土构件极限扭矩的计算提出另一种叠加方法——组合计算法。采用ABAQUS软件对构件进行数值模拟,通过三组构件的有限元模拟分析来验证组合法的准确性。利用钢管混凝土构件、箱型混凝土构件和钢骨混凝土构件的极限扭矩初步验证了组合法的准确程度与适用范围。结果表明组合法较适用于内部型钢处于有效保护层厚度内的钢骨混凝土构件。
The calculation of the ultimate torque of steel reinforced concrete members presents another superposition method - combined calculation method. The ABAQUS software is used to simulate the components and the accuracy of the combination method is verified by finite element simulation analysis of three components. The ultimate torque of concrete-filled steel tubular members, box-type concrete members and steel reinforced concrete members is used to verify the accuracy and scope of the combined method. The results show that the combination method is more suitable for the internal steel in effective protective layer thickness of steel reinforced concrete components.
