摘要
为减少行人对机动车行驶的影响,提高行人过街的安全性,人行天桥在城市道路中的重要性日益增加。通过对大跨径钢结构天桥如何提高竖向自振频率加以讨论,提出解决桥梁自振频率偏小的解决方案,确保桥梁结构安全。
In order to reduce pedestrian ＂s influence on motor vehicle drive, and improve the safety of pedestrian crossing, the importance of passenger foot - bridge in the city road is increasing day by day. By discussing the large -span steel structure bridge on enhancing vertical natural vibration frequency, the solution for solving bridge natural frequency lower is proposed to ensure the safety of bridge structure.
