Effective Control of Response of a Reinforced Concrete Building Under Seismic Loads Using Tuned Liquid Damper

Abstract

AbstractEarthquake forces are arbitrary in nature and flighty, incite vibrations in structures, which upsets the structure by expanding the energy inside the structure framework. This energy can be dispersed by the vibration control framework. With the progress in the discipline of structural engineering in the construction sector, there is a need for a skyscraper and lightweight system to reduce increasing room problems in metropolitan areas. These systems are versatile and have low damping values. Dampers of these days are pursued for vibration regulation of structures due to their protected, efficacious, and prudent design. This work is based on analytical analysis on ETABS to evaluate the optimal TLD depth ratio for an existing structure. The structure is G + 15 reinforced concrete construction with 1 basement and a TLD placed on the terrace. The TLD is used as a passive damper to reduce a structure's seismic activity when it is subjected to horizontal sinusoidal excitation. In this paper, a distinction is made using ESA and THA approach on the structure without TLD (the normal structure) and with TLD. In this work, four depth ratios 0.2%, 0.3%, 0.4%, and 0.5%, respectively, are used for estimating base shear, maximum storey displacement, storey drift, spectral displacement, and spectral acceleration have been compared. The results of this work reveals that the usage of TLD with optimum depth ratio narrow downs, the key parameters such as base shear, storey displacement, storey drift, spectral displacement, and spectral acceleration in a significant amount.KeywordsTLD (Tuned liquid damper)TSD (Tuned sloshing damper)Equivalent static analysis (ESA)Time history analysis (THA)Depth ratioETABS
