曲轴宽板桥的厚板单元分析

Thick Plate FEM Analysis of a Curved Wide Plate Bridge

本文提出了宽弯板桥的厚板单元分析方法,这种单元考虑了横向剪切变形的影响,可直接求出垂直于中面的两个方向剪力,不仅适用于厚板而且也适用于薄板的分析,文中介绍了某两跨连续弯板桥的分析结果。

This paper puts forward an analysis method for curved wide plate bridges with thick plate elements. This analysis method is quite valid. The effect of shearing deformation is considered in the thick plate elements. Both thick plates and thin plates can be analysed by using the elements. In this paper, the authors presented the analysis results for a two-span continuous reinforced concrete curved plate bridge by using the thick plate elements.
