In order to obtaining the actual dynamic properties, the actual dynamic responses and reference data of engineering design, theoretical research and numerical research of cable-stayed bridge with steel arched towers, the dynamic loading tests were carried out and studied on the Sanhao Bridge in Shenyang, which is a cable-stayed bridge with steel arched towers. The pulsating method and the forced vibration method were applied to test the dynamic properties of the bridge and the dynamic responses of the bridge in the case of running experiment, jumping experiment and braking experiment, respectively. The dynamic properties of the cable-stayed bridge, the vertical displacement responses, transverse displacement responses and stress impact factors of the main girder in each testing case were gotten using the dynamic loading tests. The testing results showed that the dynamic parameters of the bridge met relevant codes. What's more, the results could provide reference data for design of cable-stayed bridge with steel arched towers and could provide base materials and check tools for theoretical study and numerical study of dynamic analysis of the bridge.
