对计算条板柱的受压承载力的2种计算方法进行评价。测定条板柱的轴压承载力。采用著名的埃尔顿·佩里公式和极限承载力曲线方法,计算有缺陷实腹柱的受压承载力,但这些公式对组合柱的有效性还有待试验研究。几何参数包括:条板间距、尺寸及纵向弦杆的间距。结果表明:对于条板柱和实腹柱的受压承载力计算,这2种方法一般均有效。取埃尔顿·佩里和极限承载力曲线方法的平均分析结果为柱的受压极限承载力,这种方法效果最好。相比于几何尺寸,条板柱的初始缺陷对受压承载力的影响更大。
Two methods to calculate the compressive bearing capacity of slat columns were evaluated. Determination of slab column axial compression capacity. The well-known Elton Perry formula and the ultimate bearing capacity curve method are used to calculate the compressive bearing capacity of defective solid columns. However, the validity of these formulas for the composite columns remains to be studied. Geometric parameters include: spacing, size and longitudinal chord spacing. The results show that these two methods are generally effective for the calculation of compressive bearing capacity of slab columns and real columns. The average analysis of Elton Perry and the ultimate bearing capacity curve method is the ultimate bearing capacity of the column. This method works best. Compared with the geometric dimensions, the initial defect of the slab column has a greater influence on the compressive bearing capacity.
