Abstract
Seismic performance of structures can be improved using various methods. In this study, Vorspann System Losinger (VSL) Gensui Damper is used to improve the seismic performance of building with semi-rigid floors. Spectrum consistent ground accelerations is generated from El Centro May 19th, 1940 earthquake per SNI 1726:2012 for Mataram, Indonesia. Modified Simplified Sequential Search Algorithm (MSSSA) and Optimum Damper Allocation Method (ODAM) are used to efficiently place the dampers on the building to meet certain criteria. Uniform placement which is used as the first step of ODAM is used for comparison. The results show that both methods can effectively reduce structural drifts and damages. MSSSA shows slightly better performance since ODAM has a limitation that dampers can only be swapped among stories of the initially chosen frames. It is also noted that the dampers must be well distributed among frames in the same story, to take care the different drifts in building with semirigid floors.
