000009719 520__ $$2eng$$aPangu Plaza, located at Beijing close to 2008 Olympic main stadium, 191 meter, 39-story steel high-rise building，was analyzed under earthquake and wind loads by us, with both Fluid Viscous Dampers (FVD) and Buckling restrained braces (BRB or UBB), as the seismic protection system. A repeated iteration procedure of design and analysis was finished for the optimization. The complete seismic response on the horizontal and vertical directions was shown the Fluid Viscous Dampers are highly effective to reduce the structural response, as well as the secondary system response. A comparative analysis of structural seismic performance and economic effect was considered, by the traditionally increasing steel columns and beams size; increasing seismic braces versus using FVD to absorb the seismic energy. Both structural response and economic analysis results show that using FVD to absorb the seismic energy not only can make the structure satisfied the Chinese seismic design code for the “rare” earthquake，but it greatly improves the resistant capacity of seismic performance and also is the most economic way for both one-time direct investment and a long term maintenance for reducing seismic vibration..
