摘　　要：为研究钢─轻骨料混凝土组合梁变形机理，运用最小势能原理建立了不完全交互作用组合梁的变形微分方程及简支组合梁在常见荷载作用下的跨中变形计算公式，并通过试验进行论证，理论与试验结果吻合良好．The deflection characteristic of the composite beams on steel and ligh weight concrete is summarized by experimental studies, the deflectional differential equation of simply supported steel andconcrete composite beams is established, the calculating formulas of deflection are proposed for diffent loadingcases by the energy princinple. A good agreement is obtained between the calculating results and theexperiment results.
