Design and Study on Earthquake Absorption Using ViscoelasticDamper in Transportation Building of Suqian City

This paper briefly presents the structural earthquake absorption design using the viscoelastic damper for the 13 storied Transportation Building in Suqian City where the seismic design intensity is 9,with its calculation method of elasto plastic earthquake response and the main calculated resultsalso given. The calculated results show that its superstructure can be designed for intensity 8 after putting the viscoelastic dampers and its bearing capacity and the deformations can satisfy the requirements of the seismic code under normal as well as serious earthquake horizontal actions respectively.The main structural cost can be reduced by about 10%.
