FEASIBILITY STUDY OF SEISMIC RESPONSE CONTROL OF A CENTER CORE TYPE TALL BUILDING BY A NOVEL DAMPED OUTRIGGER SYSTEM WITH TUNED VISCOUS MASS DAMPERS

This paper proposed a novel damped outrigger system with tuned viscous mass dampers (TVMDs) for a Japanese tall building where the outrigger span was relatively larger than that of a typical tall building in the world. A series of generalized response spectrum analysis and nonlinear response history analysis for a typical Japanese tall building with a center core was performed to investigate the seismic response reduction effect. Moreover, the structural detail was designed to estimate the cost and cost performance index, and the feasibility of the TVMD damped outrigger system was strictly discussed.
