Abstract

Rectangular hollow sections (RHS) are widely used in construction. Strengthening of RHS is a major concern due to design errors, environmental effects, and the need to withstand increased loads. Traditional methods for external strengthening using steel plates can be a successful solution, but it has many disadvantages such as, tough in shaping and heavy weight which requires large equipment for lifting. On the other hand, non-traditional method of strengthening structures using carbon fiber reinforced polymer (FRP) did not show any of these defects. Using FRP for strengthening beams became popular and a solution for the problems facing the steel structures, because of its high tensile strength. This paper gives a quick design reference to the designers about the best way to strengthen RHS. Designers needs to know, FRP type, length, thickness and position and corresponding increase in the load carrying capacity. Three types of FRP, (CFRP) carbon fiber reinforced polymer, (GFRP) glass fiber reinforced polymer and (AFRP) aramid fiber reinforced polymer. A finite element model using ABAQUS was done using a simple beam subjected to a mid-span concentrated load. This paper gives the designer engineers a quick reference about the best way to strengthen RHS beams.
