摘　　要：完成了8个钢-闭口型压型钢板轻骨料混凝土组合梁试件的静力试验,对组合梁弯曲刚度计算方法进行研究。分别介绍了换算截面刚度法、考虑滑移的刚度折减法及修正折减刚度法这三种目前常用的组合梁刚度计算方法,并采用刚度折减法和修正折减刚度法计算了8个组合梁试件的刚度及跨中变形,并与试验结果进行比较分析,最终根据分析结果对组合梁的刚度计算方法提出建议。Static test of eight steel-light weight concrete composite heams with re-entrant trough profiled steel sheeting specimens were conducted to study the flexural rigidity of the composite beams. Based on the test results, three calculation methods of the composite beam＇s flexural rigidity were introduced. And the rigidity and span medium deformations of the eight specimens calculated by these methods were compared with the test results of the specimens, from which the calculating method of this type of composite beams~ flexural rigidity was presented and verified.
