并确定了各个构件的截面尺寸。

And to identify the various components of the section size.

因此只要有效截面取得正确公道，即可正确确定构件的整体承载能力。

If we get proper effective section, we can calculate total bearing capacity of members exactly.

因此，对厚壁双冷弯槽钢焊接组合截面构件而言，确定其稳定承载力时应考虑焊接残余应力和冷弯残余应力的共同影响。

So for thick-walled double channels with welding composite section, the combined effects of the cold-formed and welding residual stresses shall be considered to assure the stability bearing capacity.
