摘要
以G220～济青高速公路王舍人互通立交连接线工程主桥的北侧水中引桥为例,使用大型通用有限元软件ABAQUS 6.14建立组合钢箱梁的空间板壳模型,分析在均布力作用下的混凝土板和钢箱梁的剪力滞效应沿纵向的分布规律,并与纯钢箱梁以及规范规定的方法的计算结果对比,得出关于宽幅组合钢箱梁设计的几点建议.
Abstract
Taking the approach bridge on the north side of the main bridge of Wangsheren Interchange Access Project from G220 to the Jinan-Qingdao Expressway as the background,the finite element software ABAQUS 6.14 is used to establish the spatial shell model of the composite steel box girder,the distribution law of the shear lag effect under the uniform force and concentrated force is analyzed,and the calculation results are compared with those of the steel box girder and the calculation method specified in the specification.Some suggestions on the design of wide-width composite steel box girder are put forward.
