焊接薄壁箱形截面轴心压杆的承载力计算

在论证有效截面法和有效屈服强度法的相通性的基础上，建议对焊接薄壁箱形截面轴心压杆采用后一种方法计算其承载力。在用这种方法计算时，用传统的正则化宽厚比作为参数，以保证必要的可靠度。建议方法和已有试验资料做了比较。对中长压杆，试件实测承载力大多略高于计算值。

Capacity Calculation of Welded Axially Compressed Members with Thin-Walled Box Section

Basing on the argument of identity between the approach of effective section and that of effective yield strength,the latter is recommended for calculating the capacity of welded axially compressed members with thin-walled box section. The traditional normalized width-thickness ratio is to be used for calculation by this approach,so that necessary reliability can be guaranteed. Comparison is made between the suggested method and available test data. For most members of medium length,the measured capacities ...
