Краткое описание

The paper presents the results of an FE progressive failure analysis of two all-GFRP pultruded beam−column bolted joints, aimed at evaluating the moment−rotation characteristics and the failure mechanisms. Different failure criteria are adopted in the analysis and the results are compared. The failure mechanisms and the moment−rotation characteristics of the joints are compared with those of similar pultruded connections. Finally, the dissipation capacity of the joints is investigated through the evaluation of the equivalent viscous damping for hysteretic cycles. The analysis results are presented, in particular, the capability of the analysis approach and of the adopted failure criteria to simulate the failure mechanism of the joints, especially if partially interactive criteria are adopted, that allow one to distinguish between the fibers and matrix failures. Also using the Tsai-Wu criterion failure initiation is detected in correspondence of the cleats' edges. The analysis of the joints subjected to hysteretic cycles points to the availability of some dissipation capacity related to the pseudo-ductile behavior of the joints induced by the damage progression. The adopted failure criteria give similar results for the joints subjected to pure bending, while significant differences are obtained for the joints subjected to the hysteretic cycles.
