Abstract

Repairing of reinforced concrete beams by using thin fibers concrete jacket have many advantages such as increasing of ultimate load, enhancement of serviceability limit state, resistance to fire and avoiding of corrosion problems that appear in steel plate jacket. This paper reports investigations conducted to study the repairing of reinforced concrete beams subjected to short time repeated loading by using mixed steel fibers concrete jacket (MSFCJ). For this purpose, eight reinforced concrete beams have 120×300×2300 mm dimensions were fabricated and tested under three point load. The used concrete mix contains two mixed shape of steel fibers, corrugated and end-hooked steel fibers. Two of these beams were fabricated without jacket, the first was tested under static load up to failure and the second was tested under short time repeated loads up to failure. The rest six beams were loaded up to 0.5 the ultimate static load and then repaired by U-shape jacket (MSFCJ) with various thickness and steel fibers content. The test results showed the effectiveness of the proposed technique in the behavior of such beams.
