（哈爾濱建筑大學 150008）[提要] 給出了單一應力狀態(tài)下鋼管混凝土構件承載力的計算公式和復雜應力狀態(tài)構件的相關極限方程，并簡要介紹了CFST構件剛度和變形的計算公式，及混凝土徐變和收縮、環(huán)境溫度變化以及在構件上焊接的影響。
[關鍵詞] 構件 承載力 計算公式 單一應力狀態(tài) 復雜應力狀態(tài) 極限方程 剛度 變形The calculation formulas of CFST members under single stress state are derived, and the relative limited equations of CFST members under multi-stresses state are given also. The calculation formulas of rigidity and deformation of CFST members are derived. Finally, the effects of creep and sMnkage of concrete, the change of temperature for environment and the welding on the member are briefly introduced.
