Abstract
With a 10 layer of concrete filled square steel tubular column beam frame structure as the object of study ,discrete structure into multiparticle system and establish a dynamic differential equation,solve this dynamic equation by Newmark -β method .Establish thefinite element model of the structure is based on Sap2000 ,then dynamic elastic-plastic time history analysis are carried out, the research results show that the dynamic characteristics of structure,s story drifts,story shear and acceleration with energy dissipating devices are smaller than the model without energy dissipating devices under different earthquake intensities. the damped effect is considered obvious.
