钢-混组合连续箱梁桥的设计要点

Design Points of Steel-concrete Composite Continuous Box Girder Bridge

以沈阳市长青街快速路工程为背景,通过桥梁博士对40m+48m+40m跨钢-混组合连续箱梁桥进行计算分析,针对组合梁采用单梁计算模型设计过程中存在的问题和难点,提出了相应的解决方法,总结了钢混组合箱梁桥的设计要点。

Taking the expressway project of Changqing street in Shenyang as the background,the corresponding solutions are put forward through the calculation and analysis of 40m+48m+40m span steel-concrete composite continuous box girder bridge with bridge doctor program as well as the problems and difficulties in the design process of composite beam using single beam calculation model,so as to summarize the design points of steel-concrete composite box girder bridge.
