Abstract
Effects of damping matrix in the response of structures with added linear viscous dampers J.R. Arroyo \ J. Marte^ 'Department of General Engineering, University of Puerto Rico, Mayaguez Campus "Department of Civil Engineering, University of Puerto Rico, Mayaguez Campus Abstract In the last decade the use of some devices had been proposed and used to reduce the response in structures due to earthquakes effects by increasing the damping of the system. These devices are activated whenever the structure vibrates and have no effect otherwise, so it can be called passive damper. In this paper, the response of a structure with added linear viscous dampers is presented by using two damping matrix model of the system. The first damping matrix used is one with arbitrary constant producing a nonclassical damping matrix. That is, the eigensolution cannot be used to decouple the equations of motion. To solve the problem, the system of second order equations is transformed into a sys
