［摘要］型钢混凝土偏心受压构件是组合结构中的主要结构构件，其正截面受压承载力的计算方法在各国组合结构规范中都有规定。主要介绍在试验研究基础上，以平截面假定为基础建立的型钢混凝土偏心受压构件正截面承载力的计算方法，以及承载力计算值与试验实测值的比较，二者吻合良好。此计算方法已列入《型钢混凝土组合结构技术规程》（JGJ 138—2001）、《组合结构设计规范》（JGJ 138—2016）。

Abstract:The eccentric compression members of steel reinforced concrete (SRC) are the main structural members in composite structure, and the calculation method of the compressive bearing capacity of its normal section is specified in the composite structure specifications of various countries. The calculation method of normal section bearing capacity of steel reinforced concrete eccentric compression members based on the assumption of flat section were mainly introduced on the basis of experimental research. The calculation value of bearing capacity and the experimental were compared and they were in good agreement. This calculation method has been included in the Technical specification for steel reinforced concrete structures (JGJ 138—2001) and Code for design of composite structures (JGJ 138—2016).

Keywords:steel reinforced concrete eccentric compression member; assumption of flat section; bearing capacity calculation method
