分析了纵向含钢率、剪力连接件的布件方式及混凝土骨料对梁性能的影响，提出梁极限承载力的计算方法，推导出考虑钢－混凝土交界面处滑移影响的挑度计算公式．
The paper analyzes the longitudinal steel content, the manner of the fabric of the shear connector and the influence of the concrete aggregate on the beam performance. The calculation method of the ultimate bearing capacity of the beam is proposed, and the calculation of the influence of the slip effect at the steel-concrete interface is deduced. formula.
