Analysis of a Tall Structure with X-Type Bracings Considering Seismic Load using Analysis tool Staad.pro: A Review

Multistory buildings are mostly affected by earthquake force in seismic prone area. The major concern in the design of multistory building is the structure mainly to have enough lateral stability to resist lateral forces and to control the lateral drift of the buildings. The steel bracing system in reinforced concrete frames is viable for resisting lateral forces, steel bracing is easy to erect occupies less space and has flexibility in design for meeting the required strength and stiffness. To resist lateral earthquake loads, shear walls are commonly used in RC framed buildings, whereas, steel bracing is the most often used in steel structures. In the past two decades, a number of reports have also indicated the effective use of steel bracing in RC frames. Steel bracing of RC buildings started as a retrofitting measure to strengthen earthquake-damaged buildings or to increase the load resisting capacity of existing buildings. In this review paper we are presenting the past researches and their outcomes to conclude the efficiency and stability of tall structure with bracings and other lateral load resisting members.
