Investigation of Strengthening Reinforced Concrete Beam-Column Connection Wrapped with Fiber-reinforced Polymer

In reinforced concrete structures, the beam-column connection area has a considerable influence on behavior of structure. The use fiber-reinforced polymer FRP to strengthen connections in Reinforced structure can be one solutions transform this area, thus improving structure, which is achieved through carbon achieve high-strength Investigations have been conducted using finite element modeling. damage plasticity model used analyze model. results show that bearing capacity developed considerably, but ductility also significantly reduced. study evaluated qualities various reinforcement models and proposed most effective flex zone with fibers oriented at forty-five degrees shear joint showed significant changes behavior. demolition joints sudden failure without prior notice, since collapse column before break beam are undesirable, their occurrence cause irreparable damage.
