Vibration control of a Plan irregular RC framed structure under seismic excitations with the help of TMD along with bracings
Abstract: The study of dynamic behavior of high-rise structures is immensely important as the dynamic response of the structures due to natural forces like seismic forces, wind forces etc. may result in structural failure. An unsymmetrically located shear wall or similar kind of stiff element may cause the structure to have plan irregularity. Such type of plan irregularity in high rise structure can induce the torsional displacements in the structure subjected …

STUDY OF EFFECT OF SSI ON SEISMIC RESPONSE OF AN IRREGULAR RC STRUCTURE ON SLOPING GROUND AND ITS RESPONSE CONTROL BY USING BRACINGS
Abstract: Structures located on sloping terrain surface are more susceptible to earthquake because of uneven plan and elevation irregularities. Lately, high-rise buildings have been design with various plan and elevation irregularities to elevate their visual aesthetics. In the most of cases, the structural analysis under an earthquake load has been done without considering the effect of soil-structure interaction (SSI), thereby it may not reflect the actual seismic response of the structures. …
