Study of torsional behavior of reinforced concrete beams strengthened with aramid fiber strips

Reliabilty-based Torsional Design of Reinforced Concrete Beams Strengthened with CFRP Laminate

 The structural reliability of torsional concrete beams strengthened with full and strip wrapping of carbon fiber reinforced polymer (CFRP) laminate is investigated. The first order-second moment reliability method has been applied to make a reliability assessment on the torsional capacity design by technical guideline in Iran. The code No.345 published by the Management and Planning Organizati...

Behavior of Coupling Beams Strengthened with Carbon Fiber Reinforced Polymer Sheets

In this research, using the results of 6 tests, the effect of Carbon Fiber Reinforced Polymer (CFRP) sheets on the behavior of reinforced concrete coupling beams of shear walls is studied. First, in the experimental part of the study, four coupling beams with different reinforcements were manufactured and tested. Then, after the failure of the specimens, two of them were rehabilitated and stren...

Retrofitting of Reinforced Concrete Beams with Steel Fiber Reinforced Composite Jackets

In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...
