【摘要】 大型预应力预制“U”型梁是广州地铁二号线高架试验段结构的重要构件之一。本文在构件静载试验与按开口薄壁梁单元进行设计计算的基础上,运用有限元软件对“U”型梁受力状态与挠度进一步的分析验证,并提出设计建议。更多还原

【Abstract】 Large prefrabricated prestressed “U” beam is one of the most important component of Guangzhou metro. In this paper, on the base of static loading test and design of hatched and thin bar element, the loading state and deflection to “U” beam are farther analyzed and validated by use of finite element software, then design suggest is put forward.更多还原
