Behavior of RC Columns Subjected to Lateral Loads and Strengthened Using NSM Basalt and Glass FRP Bars

Abstract

Lightweight, high strength-to-weight ratio, simple installation, and noncorrosive nature combine to make FRP-based strengthening a superior alternative to conventional strengthening methods in structural civilization. However, the expensive cost of carbon fibers and the low creep rupture stress of glass fibers restricted the spread of these materials across the globe. As an alternative to glass fibers, new types of fibers known as "Basalt Fibers" are gaining worldwide attention owing to their distinct characteristics and competitive pricing with carbon fibers. Basalt fibers are made from basalt rocks, a naturally occurring substance formed when volcanic lava solidified and then froze. Because of the ease of production, this kind of FRP composite is more affordable than others of its kind. Due to the fact that they use less energy throughout the production process, basalt fibers are considered ecologically friendly. Comparing BFRP composites to GFRP composites, they provide better characteristics, including greater strength and lower density than low carbon steel. BFRP composites are anticipated to be a formidable contender among other FRP composites because of the previously stated benefits. As the strengthening and retrofitting sector has evolved, it has become more important to create innovative methods that take full use of the high strength FRP bars that are now available. Because of this, employing FRP systems
