Study on Static Strength of Circular Hollow Section (CHS) T-Joint Reinforced with FRP
The static strength of circular hollow section (CHS) T-joint reinforced with FRP (Fiber Reinforced Polymer) is studied through the experimental test and finite element simulation. Based on the reliability of the finite element simulation which is verified from experimental data, the parametric analysis is conducted by using finite element (FE) software ABAQUS. In the parametric analysis, the improvement of FRP with different bonding lengths, directions and layers on the static strength of tubular T-joints is considered. Simultaneously, the effect of two key geometrical parameters and of the tubular joints on the reinforced efficiency is also included. Based on the results of the parametric study, the effect of FRP on increasing the static strength of tubular joints is finally generalized.
