摘　　要：在 6根两跨预应力钢 -混凝土连续组合梁试验的基础上 ,对预应力钢 -混凝土连续组合梁内力重分布过程及弯矩调幅系数进行了研究 ,并提出了与普通连续组合梁相统一的弯矩调幅系数计算公式 。Experiments are conducted on six prestressed steel-concrete continuous composite beams.Based on the test results,the internal forces redistribution process and reducing coefficient of internal supporting moment are studied.The formula of reducing coefficient of internal support moment is proposed,which is universal to common continuous composite beams.The calculating results are in good agreement with the measured results.

关 键 词：钢-混凝土连续组合梁 预应力 内力重分布 弯矩调幅系数
