Title: Model Test Study of a Rigid Tied Beam and Flexible Arch Bridge
Abstract:Xincheng Huanghe River Highway Bridge is a assembled prestressed concrete tied arch bridge that has been in operation over 40 years and has evident structural vibration deterioration under the action ...Xincheng Huanghe River Highway Bridge is a assembled prestressed concrete tied arch bridge that has been in operation over 40 years and has evident structural vibration deterioration under the action of live load.To systematically study the dynamic behavior of the bridge,the model of the bridge was prepared and the dynamic tests were made.In accordance with the π principle,the frequency analogy relationship between the model bridge and actual bridge was derived,the test results of the model bridge and the measurement results of the actual bridge were analyzed and compared,which proved that the derived analogy relationship was correct and the test data were reliable.Finally,the proposal for improving the low-order natural vibration frequency and floor system rigidity of the bridge was given.Read More
