Abstract EN
The traditional strengthening methods for concrete structure (girders, beams, columns….) consuming time and could be an economical, a new modern repair methods using the Carbon Fiber Reinforced Polymers (CFRP) and Basalt Fiber Reinforced Polymer (BFRP) as a laminate strips or bars,and considered a competitive solution that will increase the life-cycle of repaired structures.
This study investigated the strengthen reinforced concrete girder.
Nonlinear analysis have been adopted to the models using FEM analysis (ANSYS) to simulate the theoretical results compared with experimental results.Using finite element packages, more efficient and better analyses can be made to fully understand the response of individual structural components and their contribution to a structure as a whole.Three type of material are used in this study as an external prestressed wire (steel, CFRP and BFRP).
The prestressed beam is modeled as simply supported beam with two concentrated point load.
The results showed that all tested strengthening beam increased the load carryingcapacity of the beams depend on prestressing force.
Obtained Result was compared for different type of beam.This study also was enlarged to include using CFRP and BFRPbarwhich are light weight and moredurable, lead to ease of handling and maintenance.
The research conducted analytical work to evaluate the effectiveness of concrete beams reinforced normally by the use of CFRP and BFRP bars.
The results showed a significant gain in the beam’s ultimate capacities using CFRP bars comparing with beam reinforced with BFRP bar and reference beam
