A Review on Effect of the Positioning of Shear Wall for Earthquake Resistance Multi-Story Building

Abstract

Earthquake is one of the major natural disasters in the world. It considered that. The damage caused due to the collapse of buildings during the earthquake is huge. The main reason for this calamity is the extirpation of manmade structures. The structure’s lack of lateral rigidity is the first reason for its destruction during an earthquake. multi-story buildings need a seismic motion for their stability. Some endeavors have been done for finding the best method to make multi-story buildings strong and stable against earthquake forces. Provision of shear wall is one of the main options to provide diaphragm, which provides lateral strength for high-rise and multi-story structures. Shear walls have proper characteristics such as stiffness and strength, which can support building to resist high lateral and vertical loads. This paper aimed to find out the optimum positioning of the shear wall in a multi-story building on the sloped ground. A reinforced concrete (RC) framed building of (G+5) story on sloping area subjected to earthquake loading in zone V is considered. The analyses and design comparison is carried out using STAAD Pro structural design software. Different cases of the shear wall at various locations of the considered building have been analyzed.

Effect of positioning of shear walls in a multi-storied building on response to earthquake

“…Lateral displacement is the horizontal movement of a building due to lateral loads such as wind or earthquake [22]. The amount of lateral displacement depends on the building's height, stiffness, mass, and the type of lateral load [23]. Excessive lateral displacement can cause damage to the building or even collapse.…”

Seismic Performance of Reinforced Concrete Buildings with Different Lateral Load

“…In addition, the plan irregularity plays an important role while considering the building models for seismic analysis. In addition, a combination of shear walls and bracings may be a good choice for the earthquake resistance design of the structure [26].…”
