RESPONSE CONTROL OF 3D IRREGULAR BUILDINGS UNDER SEISMIC EXCITATIONS USING TLCD

TLCD를 이용한 지진하중을 받는 3차원 비정형 건축구조물의 응답제어

The semi-active TLCD system is investigated for control of responses of 3D irregular buildings under seismic excitations. The TLCD system is a special type of TMD system providing a performance similar to a TMD system but offers a number of practical advantages over the traditional TMD system. The equations of motion for the combined building and TLCD system are derived for multistory building structures with rigid floors and plan and elevation irregularities. Simulation results for control of two multistory moment-resisting space structures with vertical and plan irregularities show clearly that the semi-active TLCD control system reduces the responses of 3D irregular buildings subjected to earthquake ground motions efficiently.
