Studies on elastoplastic earthquake dynamic response time-history analysis of VEDB structure

Energy dissipation is a new kind of antiseismic technology. Structural shock absorption by viscous dampers is one of the most effective energy dissipation methods. In general, viscous energy dissipation brace (VEDB) is designed by viscous damper series connected with steel brace, and it is placed between two interlayer frame posts. VEDB have excellent damping ca- pacity and it can effectively reduce structure's earthquake response. On the basis of one antiseismic strengthening and rebuilding practical frame fitted with ordinary steel brace, this paper will have an energy dissipation study on the primary frame fitted with VEDB, and it mainly studies on the elastoplastic earthquake dynamic response time-history analysis of VEDB structure.
