Abstract

Design and study on petrol hotel in Xi'an city using viscoelastic energy dissipation braces in seismic regions of intensity 8 are briefly outlined. First,the response of structure under normal earthquake design level is calculated with time history method. Considering the structure not satisfied with aseismatic requirement,viscoelastic energy dissipation braces are used for reinforcement. Then,the design of viscoelastic dampers and connected braces are summarized;and the position optimization of viscoelastic damper is presented. The results proved that viscoelastic damper can reduce the vibration response of the structure effectively through the comparison with and without viscoelastic dampers. It is a high-performance energy dissipation device.
