To evaluate the wind resistance of suspension bridge, it would be necessary to know the vibrational characteristics, such as natural frequency, mode shape and structural damping, of actual bridge. Some dynamic field tests using two special vibrators were conducted at the Ohnaruto Bridge, the Ohshima Bridge and the Minami Bisan-Seto Bridge. At the tests, the vibration of large amplitude was excited, and some interesting vibrational properties as regards natural frequencies and damping values were obtained. This paper describes the test results and some studies.
