【Abstract】 This paper summarizes the results of static and dynamic model test of a Cable-Stayed bridge, and analyses the properties of the natural vibration and anti- seismic ability of the structure.14 natural frequencies and vibration modes of the model along the lines of 3 main coordinate axes in the dynamic experiment, and the deflection and strains of the structure under different normal and transverse loads in the static experiment have been measured.The result shows that there is enough transversal and normal stiffness in the structure更多还原
