%X 针对T形分布的方钢管四肢格构柱，对其绕非对称轴的换算长细比以及弯曲屈曲临界力计算公式进行了推导，并采用有限元软件ABAQUS对T形四肢格构柱进行有限元分析，通过对有限元模拟结果与计算公式结果进行对比，最后验证了推导换算长细比的正确性。<br />
For the T-shaped square steel tubular four limb lattice columns, the calculation formulas of the converted slenderness ratio around the asymmetric axis and the critical bending buckling force are derived, and the finite element analysis of the T-shaped four limb lattice columns is carried out by using the finite element software ABAQUS. The correctness of the derivation of the converted slenderness ratio is verified by comparing the finite element simulation results with the calculation formula results.
