Seismic Analysis for Zone III, IV, V of (G+14) Multistorey Building with Bracings System Using Staad Pro Software

Abstract

Abstract: This present study focuses G +14 Simple Building model In STAAD PRO software. With beam size 300 X 400 mm and column size 400 X 500 mm this reinforced concrete building having M30 grade of Concrete and Fe415 high density steel. To study the response of building with and without bracing system. The performance of the building is analyzed in Zone III, Zone IV, Zone V. Metallic braces is the easiest of simplest way of reducing response of building which gave rise to nine models for the analysis.Model1 in -BFB- Bare frame RCC Building.Model2 in -BX1-Framed building with Bracing at the exterior side along X-direction.Model3 in -BY2- Framed building with Bracing at the exterior side along Y-direction.Model4 in -BXY3- Framed building with Bracing at the exterior side along X and Y-direction.Model5 in-BEC4- Framed building with Bracing at the exterior side around the corners. This system of bracing is used because eccentric bracing systems consist of a link element that undergoes inelastic deformation for energy dissipation. This link is possibly beam element of frame structure which is more suitable for steel structures and not for reinforced concrete structures and a shear wall is a structural panel that can withstand the impact of lateral forces on it. Lateral forces are those parallel to the wall plane and are usually wind loads and seismic loads. This building has been modeled as 3D Space frame model with six degree of freedom at each node using STAAD PRO. software for stimulation of behavior under gravity and seismic loading.
