某钢管拱人行天桥的设计与校核计算

The Design and Check Calculation of A Steel Arch Pedestrian Bridge

城市人行天桥的建造可以缓解城市不断增长的交通压力,拱式人行天桥因造型优美在城市中得到了大量采用。首先给出了某钢管拱人行天桥的主要设计指标,随后建立了有限元模型,对桥梁结构的静力、动力及稳定性3个方面进行了校核计算。在满足设计规范要求的同时,也为同类桥梁的设计与校核计算提供了参考案例。

This paper firstly presented the main design parameters of a steel arch pedestrian bridge,and then established the finite element model,it also checked and calculated the bridge structure from the statics,dynamics and stability.The paper met the requirements of the design specification,as well as provided a reference case for design and check calculation of the similar bridge.
