Abstract

The global population rise has fostered the need for high buildings, which differ from traditional buildings of limited height in their resistance to lateral loads. So now, it's critical to think about lateral loads. To prevent possible collapse, compared to wind loads, which are only 1:3 percent of the structure's weight, and earthquake loads can reach 30:40 percent [1]. This necessitated us to use reinforced concrete walls. on the other hand, the existing structures frequently need to be modified to meet modern living standards, so cutting out openings in RC shear walls is one of the most widely used improvements. This study reviews some of the most recent experimental and finite element research that has been published in the literature and lists the major contributions until 2023. Also, this paper presents a summary of some studies available in the literature concerning the mode of failure commonly observed in RC shear walls and analyzes the impact of opening attributes such as size, position, and shape on shear wall behavior. Moreover, it investigates how variables like steel reinforcement ratio and opening arrangement affect the shear wall's response to lateral loads. The influence of aspect ratio on overall performance is also explored. Additionally, the research highlights design provisions and guidelines available for cases involving RC shear walls with openings. From this study, it is clear that the width of openings plays a more significant role than the height. Also, the small openings do not affect the flexural behavior of slender walls, and the creation of openings greatly reduces cumulative energy dissipation and increases the ductility of the RC shear walls
