Abstract :
By using direct differentiation method, the algorithm for the dynamic sensitivity response of structures with Bouc-Wen restore force model was proposed; the step-by-step integration based on Newmark method was established, the convergence of this algorithm was observed and the step size of the algorithm was recommended . In the end, the displacement sensitivity responses of SDOF and 2 DOF systems with respect to parameters of Bouc-Wen model were observed. All of the works are important for further studies.
