摘要：In this paper, an approach is developed based on the force analogy method to analyse the dynamic response of structure with energy dissipation devices (EDDs). The proposed algorithm is applicable to a variety of EDDs by turning the EDD to the equal force imposed on the joints of frame. Compared to the conventional method for a nonlinear deformation analysis using changing stiffness, this analytical method is superior with features such as significantly reducing the integration times owning to the nonlinear characteristic of the EDD, dramatically enhancing the velocity of calculation and remarkably expanding the amount of the solution information. Besides the dynamic analysis of structure, the new proposed algorithm also accurately captures distributions of plastic hinges and the plastic displacement at any time before and after the EDDs installation. Compared to the numerical results obtained by use of the finite element software ANSYS, the approach here is verified to be accurate and efficient. Copyright (c) 2009 John Wiley & Sons, Ltd.
