L形钢管混凝土短柱的轴压承载力简化计算
Simplified Calculation of Ultimate Strength for L-Shaped CFT under Axial Loading

本文将L形截面钢管混凝土柱划分成一个方形和两个矩形钢管混凝土柱，合理假设截开面上的边界条件，建立了该类构件的力学模型；并借鉴我国规范对方形、矩形钢管混凝土柱承载力的规定，提出了L形钢管混凝土短柱在轴向荷载作用下的计算公式；并用建议公式对相关试件进行计算，计算结果与试验结果吻合良好。
In this paper, the L-shaped concrete-filled steel tubular column is divided into one square and two rectangular concrete-filled steel tubular columns, and the mechanical model of this kind of member is established by reasonably assuming the boundary conditions on the cutting surface; the calculation formula of L-shaped concrete-filled steel tubular short columns under axial load is put forward by referring to the provisions of Chinese codes on the bearing capacity of square and rectangular concrete-filled steel tubular columns; the proposed formula is used to calculate the relevant specimens, and the calculated results are in good agreement with the test results.
