STRUCTURAL JOINTS MADE BY FRP AND STEEL: A NEW PROPOSAL OF ANALYSIS BASED ON THE PROGRESSIVE DAMAGE APPROACH
要約
The work aims to investigate the nonlinear behavior of pultruded joints and the related dissipation capacity through a three-dimensional FE progressive failure analysis of different GFRP beam-column and column-base bolted connections. Different failure criteria are adopted in the analysis and the results are compared. The failure mechanisms of the joints are discussed and the dissipation capacity is evaluated through the computation of the equivalent viscous damping coefficient related to the nonlinear hysteretic behavior. For the column-base joint, the influence of the axial load on the joint's nonlinear behavior is also investigated. The adopted analysis approach appears able to realistically simulate the failure mechanism of the joints. The analysis of the joints subjected to hysteretic cycles evidences a low dissipation capacity, while the analysis of the column-base joint puts in evidence the significant influence of the axial load on the connection's behavior.
