摘要
人行天桥在城市交通中占据了不小的比例,而结构的安全性和舒适性是设计的重点。以临湘六中人行天桥为例,通过建立主桥空间有限元模型进行计算分析。结果表明,采用全焊接的钢桁架结构形式,既满足了学校人行天桥人流量大且集中的受力要求,又实现了理想的景观效果。
The footbridge occupies large proportion in city traffic,the safety and comfortableness of the structure is the focus of the design.Take Linxiang No.6 high school footbridge as example,the article has calculated and analyzed through the establishment of the main bridge space finite element model.The results showed that,the adoption of all-welded steel truss structure could not only meet the requirements of a school's massive human traffic and centralized force,but also achieve an ideal landscape effect.
