摘　　要：由于组合梁交界面滑移的存在,随着剪力连接程度的降低,部分剪力连接钢—砼组合梁变形会显著增加,精确计算也变得非常困难和复杂。本文在曲率微分方程和滑移应变微分方程的基础上,采用两种不同的方法,建立了精确计算部分剪力连接钢—砼简支组合梁变形的一般公式,得出了部分剪力连接简支组合梁的变形和附加变形与剪力连接程度系数之间的关系与规律,公式简单、实用。对其它类型的部分剪力连接组合梁变形分析也具有很高的指导意义。On account of the slips in the interface, the deflection of the steelconcrete composite beams with partial shear connection increases notably with decrease in the shear connection degree, and it is very difficult and complex to predict it accurately. Basing on the differential equations of curvature and slip strain, this paper sets two general formula to predict the deflection of simply supported steelconcrete composite beams with partial shear connection by two different methods, and puts forward the relationships and laws between the deflection and additional deflection of beams and the shear connection degree coefficient. All general formula are simple and practical, they have a well guideline to predict accurately the deflection of other types of composite beams too.
