Investigating the Impact of Novel" Damper Systems in Tall Reinforced Concrete Structures to Mitigate Earthquake Forces

Abstract

This paper investigates the impact of novel damper systems on reducing seismic forces in tall, reinforced concrete (RC) structures. Due to their height and flexibility, tall buildings are highly vulnerable to severe earthquakes. The primary objective of this research is to analyze and compare the performance of three types of dampers: viscoelastic dampers, friction dampers, and tuned mass dampers (TMD) in improving the seismic behavior of tall structures. Advanced numerical methods and dynamic analyses were performed using software such as SAP2000 and ETABS to assess the effectiveness of these dampers.

Initially, three-dimensional models of RC buildings with different characteristics were designed and simulated. The dampers were installed separately and in combination within the structures, and their dynamic performance under varying seismic load intensities was evaluated. The results indicate that viscoelastic and tuned mass dampers significantly reduce the seismic response of the structures, while friction dampers demonstrate superior performance in reducing plastic deformations.

This research concludes that the use of dampers can substantially mitigate earthquake-induced damage and enhance the safety of tall RC structures. It is recommended to incorporate a combination of these dampers in the design of future tall buildings, depending on the seismic conditions and structural characteristics.
