Energy dissipation and recovery in web–flange junctions of pultruded GFRP decks

The energy dissipation capacity resulting from progressive cracking and the recovery after unloading of the web–flange junctions (WFJs) of a pultruded GFRP deck were experimentally investigated. Web–cantilever bending experiments up to failure were performed on two WFJ types (If-o, Ic-o) with similar geometry and fiber architecture but different initial imperfections (deviations from the fiber architecture design, wrinkling of fabrics, resin...
