An investigation for enhancing seismic performance of high-rise buildings using fluid viscous damper (FVD)

Recently, the demand of construction of high rise building rapidly increases due to increase in population. Effective structural systems are imperative for these structures to withstand lateral loads, especially in earthquake-prone regions. To mitigate vibrations induced by such loads, various dampers like tuned mass dampers, friction dampers, viscous dampers, and hybrid dampers have been increasingly employed. The behavior of damper depends on arrangement in various positions in building. In this study fluid viscous damper (FVD) is provided in G + 30 Storeys high-rise RCC building to decrease vibrations and lateral deflection of building. 30 storey building has modelled in ETABS (2018). IS 1893–2016 code based methods are implemented to determine seismic responses like displacement, storey drift, base shear etc. of building with and without FVD is determined by methods based on IS 1893–2016. This study is focuses to obtain optimum positions of dampers in building and investigation of benefits of dampers by using PYTHON. The analysis is done by Response spectrum method. Obtained results are compares. From result analysis, it is found The displacement of building with damper gets reduced by an average 48.76,drift by 49.97% and base shear increases by 45.47% resp. FVD at all Storeys at center on x position and X bracing gives better performance.
