When openings are required for existing shear walls for the placement of staircases, windows, doors and elevators for the purpose of remodeling, the overall structural capacity and integrity of the wall is decreased along with stress concentration around the opening. The basalt fiber incorporated with concrete with a volume content of 0.5%( 13.0 kg/m 3 ) is used to strengthen the Rc shear wall to improve the behaviour of the structure under lateral loading. Finite element analysis for six RC shear wall models were subjected to lateral load carried out to investigate deformation, load carrying capacity and stresses that occur during loading. Three Rc shear wall models, one with solid shear wall and other two with a ordered opening and a staggered opening were analyzed without any strengthening and other three strengthened with Basalt Fiber Reinforced-Concrete. From the results, it is observed that the shear walls strengthened with basalt fibers shows better seismic performance than the unstrengthened shear wall. The load carrying capacity of Rc shear wall is greatly improved. Keywords: Reinforced Concrete shear wall, Basalt Fiber Reinforced-Concrete, Lateral load, Load carrying capacity, Deformation. I. INTRODUCTION One of the most widely used lateral load structural resisting elements in high rise buildings are Reinforced Concrete Shear wall and its main function is to increase the rigidity and strength of the building for lateral resistance. Shear walls have very high in-plane stiffness and strength, which helps in resisting large horizontal loads such as seismic or wind forces along with resisting gravity loads. In order to avoid brittle shear failures RC shear walls must be carefully designed to provide adequate strength and sufficient ductility. Due to poor design and detailing several shear walls all over the world are suffering damages from earthquakes. Due to remodeling or municipality considerations, such as placement of staircases, windows, doors and elevators openings are provided in existing shear walls which results in the decrease of the overall structural capacity and integrity of the wall, in addition to stress concentrations around the openings. The number and size of openings affects the load carrying capacity as well as stress in the shear wall. Basalt Fiber Reinforced-Concrete is used as a strengthening material to improve the behaviour of shear wall with openings. The Basalt Fiber Reinforced Polymer is a new inorganic material, which is low in cost when compared with Carbon Fiber Reinforced Polymers and also has excellent physical and mechanical properties, such as light weight high tensile stress and it also provides an advantage over CFRP in terms of ductility, of which ultimate strain is less than that of BFRP. It is one of the benefits for RC members to maintain ductility during seismic events. As a new fiber reinforced material, It has a good perspective in the area of seismic strengthening for its low cost and exhaustive mechanical properties. The mechanical properties of Basalt Fiber Reinforced Concrete were collected from the experiment conducted by (Kirthika & Singh, 2018). In this study, Finite element analysis is carried out for six shear wall model using ANSYS software ( release 2020 R2). Elastic and Plastic deformations were simulated which would happen in concrete and Reinforcement.
