摘要
提出一种板桁结合梁剪滞效应分析的有限段单元模型 ,避免了常规计算方法中的某些不足。利用势能驻值原理和“对号入座”法则建立了单元刚度矩阵 ,对芜湖长江大桥斜拉桥部分进行了实桥分析 。
A kind of finite segment element model for analysis of shear lag effect in plate and truss composite girder is proposed. The model avoids certain deficiencies in conventional calculations. By using principle of minimum potential energy and “Set in Right Position” Rule presented early by Zeng Qingyuan, the stiffness matrix of the element is derived. With the method described in the paper, the part of cable stayed spans of Wuhu Changjiang River Bridge is analysed, and some conclusions drawn therefrom can be referred to in design of similar types of bridges.
