Steel angles and strips jacketing method is the popular structural local strengthening technique for existing deficient RC columns. Although this strengthening technique is well accepted, limited research is carried on the actual strength and behaviour enhancement of the deficient RC columns due to the application of this particular steel jacketing method. This study primarily intends to review the experimental and numerical works on the steel angles and strips jacketing method used for deficient RC columns available in published literature. This study also intends to present the variables which have considerable influence on the strength and behaviour enhancement of the deficient RC columns for this structural local strengthening technique.
Ridesharing in Bangladesh began on May 7, 2016, with the launch of an app called "Share A Motorcycle," or SAM. The current and future issues of Dhaka City's motor ride-sharing services are examined in this paper. With a sample of 570 or more consumers or users, the present state andpotential are examined. A total of 570 people have responded to the survey. Because of its specific advantages,Because of its real-time catalyst, more convenient, ondemand position, and consumer, it has garnered widespread favor among the younger generations and enterprises. Concerns about funding, a lack of logistical support, a lack of understanding, bad government regulations, fierce rivalry, and other problems have all been highlighted as major roadblocks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
