摘要
按照现行规范考虑板的有效工作宽度下的板的理论算法、不考虑腹板支承宽度下的平面杆系算法、考虑腹板支承宽度下的平面框架算法三种算法,以一单箱双室连续梁为例,选取两典型断面,分别验算了其悬臂根部、腹板支点、箱室跨中几处在最不利横向布载下的弯矩内力值。通过比较得出了有益的结论,为今后桥梁设计工作提供一些参考。

JIANG Zhi-feng, YUN Yu (JSTI Group, Nanjing 210000, China sideri the ng the three algorithms according to the current criterion, incJuding the effective working width of the plate, the bar system algorithm without considering the width of plate support, the algorithm for plane frames considering the width of plate supports. Taking a single box double chamber continuous beam as an example, two typical sections are selected, and the moment internal force values of the cantilever root, the web fulcrum and the misspend of the box room under the most unfavorable lateral loads are checked respectively. Some useful conclusions are obtained, which can provide some reference for bridge design in the future by comparison.
