Nghiên cứu kết cấu bê tông cốt thép được tăng cường bởi tấm vật liệu tổng hợp composites theo phương pháp dán trên bề mặt

Abstract

Externally bonded fiber reinforced polymer (FRP) composites method has become a popular technique for strengthening concrete structures in the world. The performance of the interface between FRP – epoxy – concrete is one of the key factor affecting the behavior of the strengthened structure. Analysis for this kind joint is relatively complicated. Abaqus software has been used to simulate three-dimensions a pull – out externally bonded FRP – to – concrete joint. Through this simulation, stress and deflection in bonding system would be investigated.
