Abstract

Abstract: By computing the twisting moment of one cap beam by traditional and finite element method respectively ， the diferences between the two methods are got．A conclusion is drawn that the traditional method is to conservative to determine the twisting moment of cap beams．while the finite element method is relatively reasonab1e.

Key words: pier cap beam, twisting moment, twisting resistance capacity, spatial beam element.

摘要： 通过分析用常规计算方法和有限元算法对同一桥墩进行扭矩计算结果的巨大差异，得出了常规算法过于保守，不利于客观地评定盖梁的抗扭承载力，同时也说明了用空间梁单元，计算盖梁扭矩的合理性．

关键词: 桥墩盖梁, 扭矩, 抗扭承载力, 空间粱单元.
