| Abstract: | In the past in order to save emulation efforts in the seismic response analysis of a framed structure the frame is always simplified to a series multidegree-of-freedom system. A difficult problem in analysis is how to accurately determine the rigidity coeffficients of this system. In this paper,to detemine them we present a parameter identification method in which the influences of various factors in the original structure are considered and all assumptions are abandoned in order to make the simplified system more accurately coincide with the original structure and the caicu-latinal accuracy of dynamic response be heightened. |
