摘要：
Results of a pushover analysis of GFRP pultruded frames aimed at the evaluation of their overall ductility are presented. It is assumed that the dissipation capacity of the frame structures is concentrated in joints due to their nonlinear behavior induced by progressive damage, while a brittle-elastic behavior is assumed for frame members. A two-storey one-bay GFRP pultruded frame is considered for a case study in which the column-base and beam-column joints are modeled with nonlinear rotational springs with different moment-rotation laws derived from experimental results available in the literature. For comparison, frames with hinged connections and moment-resisting frames are also analyzed. Finally, the results obtained are compared with those for a similar steel frame. The final results bear witness, in particular, to the absence of a significant ductility of pultruded frames and the relevant influence of the characteristics of bracings on their structural response.
