A Review on Earthquake-Resistant Design of Multibay Multi- Storey RC Frame Structures

Abstract

The devastating impact of earthquakes across the globe has highlighted the vulnerability of inadequately designed structures, emphasizing the critical need for earthquake-resistant construction practices. In this context, multistorey reinforced concrete (RC) frame buildings, especially in high seismic zones, must incorporate advanced structural elements to enhance resilience. This review focuses on the effectiveness of incorporating seismic resistance technologies such as shear walls, steel bracing systems, and energy-dissipating devices (viscous and friction dampers) in G+5 (six-storey) RC frames. A case model with a total height of 18 meters is analyzed using ETABS software under seismic Zone V conditions, employing linear static and dynamic analysis techniques. Results demonstrate significant reductions in storey displacement—from 39 mm to 19 mm (a 51% decrease)—and storey drift (up to 55%) when seismic mitigation systems are introduced. These findings underline the importance of integrated seismic design in ensuring structural stability and minimizing earthquake-induced damage.
