摘要：Physical model tests are conducted to simulate ice-induced vibration of flexible structures by using a new non-frozen breakable synthetic material. Responses of the structure, including acceleration, displacement and strain, are recorded as ice sheet acting on the structure with different velocities. According to the dynamic load identification technique developed by the authors, time histories and Fourier spectrum of global ice load exerted on the elastic model structure are given. Some photos recording the ice failure process as well as the measured time histories of structural responses are presented. The phenomena and results are similar to the field observations, and some features different from those of ice-induced vibrations of column structures were obtained.
