Study On Dynamic Analysis Method And Optimum Design Of Structures With Supplemental Viscous Damping

In tradition structure ,there are such typical members as beam, column, plate, wall, shell, and cable. Due to absorbing excessive earthquake energy, some members may enter into elastic-plastic state, even yield or fail under strong earthquake, with a consequence of repair failure later or direct collapse .Dampers added to structures are responsible for consuming energy introduced by earthquake or other dynamic inputs. The supplemental energy dissipation systems can be used to control story drift , improve or upgrade the structural seismic performance of new or existing building. This technology has been becoming one tendency of earthquake engineering research and practice .Scholars and engineers of this domain in many countries are being engaged in this field of research and practice . In the paper seismic response and optimum design of structures with supplemental viscous damping. The main research contents and conclusions are as follows :1. From structures with supplemental viscous damping, based on nonlinear dynamic equation, the paper creates a new equation;2. using the paper's equation, for facilitating and using in design of projects, the paper set up a means and compiles a Matlab program which results is right to exactitude results;3. For optimizing viscous damping, In this paper, Optimizing Design Method which is based on maximum relative story displacement is regarded as objective function, which results is good;4. The paper gives two practical projects which prove the paper method is feasible.
