Abstract:In this paper, a approach is developed based on the force analogy method (FAM) to analyze the dynamic response of structure with energy dissipation devices (EDDs). The proposed algorithm is applicable to variety of the EDDs through including 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 reduces the integration times owning to the nonlinear characteristic of the EDD, dramatically enhances the velocity of calculation, remarkably expands the amount of the solution information. Moreover, besides the dynamic analysis of structure, the new proposed algorithm also accurately captures the distribution of the plastic hinges and the plastic displacement at any time before and after the EDD installation. In comparison with the numerical results obtained by use of the finite element software ANSYS, the approach here is verified to be accurate and efficient. ? 2010 Taylor & Francis Group, London.
