摘　　要：根据钢骨混凝土构件受力分析的一般叠加法 ,分析了钢骨混凝土梁正常使用阶段的内力分配规律 ,推导了其抗弯刚度计算的内力分配法。该方法概念清楚、计算简便 ,且与试验结果吻合较好。Based on the general superposition method for steel reinforced concrete members, the decomposition of internal forces of concrete and steel parts under service loading was analyzed for SRC beams. A simple calculation method was suggested to determine the internal forces of concrete and steel parts. With internal forces determined, the flexural stiffness was easily obtained based on the superposition concept. The suggested method was found a good agreement with the test and theoretical results.
