大跨度钢箱梁人行天桥设计

该文分别采用有限元梁单元法和板单元计算方法,就其上部结构主梁、下部墩的设计数据作对比验算,并着重考察了各设计工况下墩顶局部应力,总结了此类结构的设计经验,并对控制设计的温度力、自振频率及局部应力,提出了切实有效的处理办法。

Design of Large-span Steel Box Beam Pedestrian Overpass

The main span of a large- span steel box beam pedestrian overpass is large and its deck is wide, which is the largest characteristic of this municipal engineering. The article separately uses the finite element beam unit method and the plate unit calculation method to contrast and check the design data of the superstructure main beam and the sub- pier, and focuses on reviewing the partial stress on the top of the pier under various conditions of design and construction, sums up the design experience of this...
