A review of moment–rotation tests on bolted connections between pultruded Glass Reinforced Plastic (GRP) Wide Flange (WF) sections highlights the lack of test data on column–base connections. Details of five bolted web and web and flange cleat connections and the test rig used to determine their moment–rotation characteristics are given. Moment–rotation responses are then presented for each connection. Simple models are described for predicting their initial rotational stiffness, ultimate moment and moment–rotation response. The models predict the response of bolted web and flange cleat column–base connections reasonably well and may be useful for design.
