钢─混凝土组合梁在受弯承载力和变形许可的条件下采用部分剪力连接对于方便施工和降低造价等都是有利的。部分剪力连接对组合梁的受弯极限承载力和变形均有影响。本文通过对4根部分剪刀连接组合梁的试验研究和对国内外8根部分剪力连接组合梁受弯极限承载力的分析，建立了考虑剪力连接程度影响的组合梁受弯极限承载力计算公式。结果表明，按照本文公式得到的计算值与实测值吻合良好。
The use of partial shearing connection of steel-concrete composite beams under the conditions of flexural bearing capacity and deformation allowance is advantageous for convenient construction and cost reduction. Partial shear connection has an impact on the ultimate bearing capacity and deformation of composite beams. In this paper, by means of the experimental study on four partially shearing composite beams and the analysis of ultimate bearing capacity of composite beams with eight partial shear connections at home and abroad, the ultimate bearing capacity of composite beams considering the effect of shear connection is established formula. The results show that the calculated value obtained by the formula in this paper is in good agreement with the measured value.
