摘　　要：提出了一种夹层玻璃板的一阶剪切变形位移模式,由此建立了静力计算和自由振动的八结点有限等参单元公式。同时本文将“频率变化比”方法应用到夹层玻璃板PVB损伤检测中,用推导出的有限元公式建立了频率变化比法的分析过程。In this paper, a first-order shear deformtion mode of laminated glass plate is presented and consequently eight-node finite element equations on static computation and free vibration are derived. Meanwhile, the ＂frequency change ratio＂ is appfied to the PVB damage detection of laminated glass plate and the analysis process is established by using the finite element equations gained.
