TÓM TẮT
Large thin-walled cylindrical steel storage tanks (CSSTs) have been widely used in many fields as fluid tanks, chemical, electric power, food engineering, etc. They play important roles in the development of economy and infrastructures. However, a large number of CSSTs have appeared increasing signs of deterioration and reducing load-carrying capacity because of corrosion or ageing degradations. In order to achieve the sustainable development of the economy and infrastructures, these existing tanks need to be strengthened. The conventional method often involves adding of heavy and bulky plates that are difficult for fixing and can interrupt the production. In recent years, the use of carbon fiber reinforced polymers (CFRPs) with many outstanding characteristics such as lightweight, high strength, and high corrosion resistance to increase the load capacity and ductility of steel structures proved to be an economical and reliable strengthening solution. In this paper, the strengthening effects of the angle of carbon fiber on the increase of the load-carrying capacity of CSSTs will be investigated under bending shear loads.
