Seismic Response Study of Reinforced Concrete Buildings Under the Effect of Varying Frequency Content

Abstract

Earthquake causes damage to living things particularly people and harms the fabricated and common habitat. Keeping in mind the end goal to play it safe for the death toll and harm of structures because of the ground motion, it’s essential to sense the qualities of the ground motion. The most essential unique qualities of seismic tremor are peak ground acceleration (PGA), frequency content, and duration. These qualities play a vital role in respect to the response of structures under seismic loads. The quality of ground motions is estimated in light of the PGA, frequency content and to what extent the shaking proceeds. Ground motion has distinctive low, intermediate, and high-frequency contents. Current research involves studying seismic frequency components of reinforced concrete structures. Time history analysis is performed in the extended three-dimensional analysis of building system (ETABS) software. The proposed strategy is to think about the response of low, mid, and high- rise reinforced concrete buildings under low, intermediate, and high- frequency content ground motions. The response of the structures because of the ground motions as far as displacement, velocity, acceleration, and base shear is found. The reactions of each ground motion for each sort of building are contemplated and looked at. The outcomes demonstrate that low-frequency content ground motions have the noteworthy impact on both regular as well as irregular RC structures. However, high-frequency content ground motions have very less effect on responses of the regular as well as irregular RC buildings.
