Study on Analysis of Fiber-Reinforced Concrete Shear Walls with Openings

Abstract

High-rise buildings employ shear walls as structural elements to withstand lateral forces brought on by earthquakes and wind. According to number of studies, shear walls function effectively when devoid of openings, although openings are essential to meet diverse functional needs such as doors, windows, staircases, and service ducts. Therefore, the presence of openings impacts the structural strength. 11 multi story buildings with 12 story with symmetric plan of 25mX25m are analyzed in this study in ETABS to compare its story displacement, storey drift, storey shear and storey stiffness between without and with vertical or regular as well as staggered openings in the shear walls placing shear wall at corner and center of the structure. Furthermore, the model with effective strength is analyzed by changing the size of openings in the shear wall. This study focuses on replacing the shear wall's concrete with fiber-reinforced concrete in order to strengthen the larger openings in the wall.
