“…Seismic response analyses for the entire structure with the dampers, and for the secondary system Soong and Chen, 1989;Soong et al, 1989a, b;Chen and Soong, 1988a, b), subjected to minor, moderate and rare earthquakes as specifi ed in the Chinese Seismic Code, respectively, shows that the responses of the structure were signifi cantly reduced (Chen and Cao, 2009). In the seismic response analysis and economic analysis following four cases were considered and compared:…”

Performance analysis of the Pangu Plaza under earthquake and wind loads is described in this paper. The plaza is a 39-story steel high-rise building, 191 m high, located in Beijing close to the 2008 Olympic main stadium. It has both fl uid viscous dampers (FVDs) and buckling restrained braces or unbonded brace (BRB or UBB) installed. A repeated iteration procedure in its design and analysis was adopted for optimization. Results from the seismic response analysis in the horizontal and vertical directions show that the FVDs are highly effective in reducing the response of both the main structure and the secondary system. A comparative analysis of structural seismic performance and economic impact was conducted using traditional methods, i.e., increased size of steel columns and beams and/or use of an increased number of seismic braces versus using FVD. Both the structural response and economic analysis show that using FVD to absorb seismic energy not only satisfi es the Chinese seismic design code for a "rare" earthquake, but is also the most economical way to improve seismic performance both for one-time direct investment and long term maintenance.
