摘要
以一座典型钢结构人行天桥为例,详细介绍了钢结构人行天桥主梁、梯道梁、墩柱、桩基等各结构的设计计算。按照相应规范对荷载效应进行组合,验算了上部结构与下部结构的强度与稳定性,同时验算了桩基础的承载力,计算分析结果表明各项设计指标均满足相应规范要求。算例可为类似钢结构人行天桥的结构设计与简明计算提供相关参考。
Taking a typical steel pedestrian overcrossing as an example, this paper introduced the design and calculation of main beam, stairway beam, pier column, pile foundation and other structures in detail.According to the corresponding specification, it combined the load effect and checked the strength and stability of the upper and lower structure and the bearing capacity of pile foundation. The calculation and analysis results showed that the design indexes met the corresponding requirement specification. It could provide relevant reference for structure design and concise calculation of similar steel pedestrian overcrossing.
