摘要
以蒲阳河一号桥项目为例,详细介绍了该异型钢桁架人行桥的总体设计,并计算了结构的受力,验算了结构稳定与自振频率,结果显示该桥梁强度、刚度、稳定与自振频率均满足规范要求,结构安全可靠。
Taking Puyanghe No.1 bridge engineering as an example,it specifically introduces the overall design of the footbridge with heteromorphosis steel truss,calculates its structural stress,and tests its structural stability and self-vibration frequency.Results show that： the footbridge strength,stiffness,stability,and self-vibration frequency all meets the demands,and the structure is safe and reliable.
