Effect ofthe Distance between Points Load on the Behavior of Strengthened Reinforced Concrete Beams
Abstract
The general behavior of the reinforced concrete beams depends on many variables, including what is the quality of the concrete and strength and including those on reinforcement type and quantity of reinforcement in the beam. But there is an important variable which nature of loads application on the beam and type of load is it point or distributed. Sometimes the distance between points load is variable such as vehicle wheel load because each vehicle as different distance between wheels.
In this research, the effect of changing the distance between the points load were studied and compared with model carrying a single point load at mid span, as well as studying the effect of the use of carbon fiber with a length equal to the distance between the points load.
Theoretical results consists of eight models were compared in this study with the results of the previous experimental results. The study contains a discussion of the general behavior of the beam in addition to the study of the failure carrying load, cracking load, ductility and the relationship between the stages of load application and the deflection of concrete beams with and without carbon fiber sheets.
Key words: Ansys, strengthening, ductility, carbon fiber.
