摘要： 利用变分理论,建立组合板界面剪力的计算微分方程,给出均布荷载下的界面剪力计算公式.计算结果表明,组合板最大界面剪力发生在跨中,并沿组合板跨度方向向端部呈非线性逐渐减小;组合板界面剪力随着连接刚度及外荷载的增加而增加,随着钢的面积分数的增加、混凝土强度等级的提高而减小;连接刚度与外荷载是影响组合板界面剪力的主要因素.

Abstract: Based on the variational principle, the differential equations are derived to calculate the interfacial shearing force of a steel-concrete-steel sandwich panel with a formula given to calculate the interfacial shearing force under uniformly distributed load. The calculated results show that the mid-span shearing force is maximum, and it decreases nonlinearly along the span gradually and approaches zero at the end. On the other hand, the interfacial shearing force increases with the stiffness of connections between the two steel plates and external load but decreases with the increasing steel content of the board and concrete strength. The main influencing factors on the interfacial shearing force are the stiffness of connections and external load.
