［摘要］型鋼混凝土偏心受壓構(gòu)件是組合結(jié)構(gòu)中的主要結(jié)構(gòu)構(gòu)件，其正截面受壓承載力的計(jì)算方法在各國(guó)組合結(jié)構(gòu)規(guī)范中都有規(guī)定。主要介紹在試驗(yàn)研究基礎(chǔ)上，以平截面假定為基礎(chǔ)建立的型鋼混凝土偏心受壓構(gòu)件正截面承載力的計(jì)算方法，以及承載力計(jì)算值與試驗(yàn)實(shí)測(cè)值的比較，二者吻合良好。此計(jì)算方法已列入《型鋼混凝土組合結(jié)構(gòu)技術(shù)規(guī)程》（JGJ 138—2001）、《組合結(jié)構(gòu)設(shè)計(jì)規(guī)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
