摘要
以绥化市诺敏河大桥加固后静动载试验为工程依托,通过荷载试验评估该钢筋混凝土T型梁桥的承载能力和使用性能,分析比较了在静载作用下跨中截面挠度和应变,以及动载作用下结构的冲击系数、自振频率、振型和竖向阻尼比。
The project relies on the static and dynamic load tests on Nuomin River Bridge in Suihua city. Through the load test, the load-carrying ability and usage performance of the reinforced concrete T girder bridge were evaluated. The deflection and strain in the cross section under static load, the impact coefficient of the structure under dynamic load, natural vibration frequency, vibration modes and vertical damping ratio were compared and analyzed.
