Energy dissipation in web-flange junctions of pultruded GFRP decks

The energy dissipation capacity resulting from progressive cracking of the web-flange junctions (WFJs) of a pultruded GFRP deck system was experimentally investigated. Web-cantilever bending experiments up to failure were performed on two WFJ types (IfO, IcO) with similar geometry and fiber architecture but different initial imperfections. The latter resulted in different load-displacement behaviors (linear and markedly nonlinear up to failure...
