  • 摘要: 利用能量变分法,建立了槽型宽翼受压构件考虑剪力滞效应时的平衡控制微分方程,给出了该方程在轴向均布载荷作用下的初参数解,导出了求解槽型宽翼受压构件内力、应力和位移的场矩阵和点矩阵,提出一种研究槽型宽翼受压构件剪滞效应的传递矩阵法. 数值算例表明,该方法计算便捷、精度好、具有较高的工程应用价值.

     

    Abstract: Based on the energy variational principle, the governingdifferential equations and the boundary conditions of a beam-and-slabstructure under axial loads are derived, with shear lag effect being takeninto account. The initial-value solutions of the equations under a uniformlydistributed load are obtained. The field matrix and point matrix arederived, by which the inner force, stress and displacement can be recursively calculated. A transfer matrix method for shearlag analysis of a beam-and-slab structure is put forward. The computationexample shows that the method proposed in the paper is valid and effective.
