Abstract

The energy dissipation structure is set up in certain parts as energy dissipation device, which consumes most energy caused by the earthquake to reduce the seismic response of structures. Based on the study of additional metal dampers and generating calculation method of equivalent damping ratio, vibration differential equations and computer programs are established. Taking damping ratio fk as a parameter and structure period Tf as a independent variable for elastic-plastic time history analysis, change rules of the particle displacement and the absolute acceleration response value are discussed. Thus the following conclusions are obtained: (1) The smaller structure period and the larger Stiffness ratio will lead to the better displacement damping effect. (2) When fk is at the range of 1 to 6, acceleration response value decreases and gains the smallest value as fk is 4; when fk is at the range of 7 to 10 acceleration response value does not decrease all the time.
