本文提出了一個非對稱結構模型的系統識別方法。該方法顯示,針對任一指定的樓層,當其上下樓板的位移反應及構件的位置已測得時,該層樓構件的勁度與阻尼係數可同時被識別出。文中並以一數值模型驗證了此方法的正確性。 在論文中,吾人推導出一組新的識別公式。並且,所使用的推導方法較其他研究者來得簡單。藉由本文可知,此推導方法應用於有扭轉耦合效應建築結構之系統識別時亦十分有效。 In this thesis we present an identification method of a class of asymmetric-plan, multi-storey buildings. It is shown that the stiffness and damping coefficients of the resisting elements at a specific storey can be identified simultaneously when the locations of these elements are known and the displacement responses are recorded at the floors just above and below the storey. A numerical simulation model is provided to verify the accuracy of the present identification method. The identification formulae we derived in this thesis are new. And the approach we used is simpler then those proposed by other researchers before. In this thesis it is demonstrated that our approach is also efficient in the system identification of torsionally coupled buildings.
