摘　　要：本文根据5个不同截面尺寸、不同钢骨含钢率的钢骨混凝土梁的抗弯性能试验,对5个试件的挠度进行了全截面弹性工作阶段、纵筋和钢骨弹性工作阶段、极限荷载阶段的分析和计算。同时对由叠加法计算钢骨混凝土梁的公式按三个阶段进行了修改、补充,给出了综合影响系数α、截面塑性发展系数β的取值。According to the analysis of five steel encased concrete beams with different size and steel ratio, the comprehensive analysis and computations have been done based on the elastic work stage, the steel and bars elastic work stage and ultimate load stage. The superposition stiffness formulas are modified and supplemented according to the three stages, the synthetic influence coefficient α and the section plastic development coefficient β are also provided.
