Abstract

This paper presents an experimental investigation into the static performance of an all-composite modular composite beam under positive and negative bending moments. The deck was fabricated using lightweight pultruded GFRP box profiles adhesively bonded between two GFRP flat plates, adhesively bonded onto two FRP I-girders. A bidirectional pultrusion orientation was present within the deck structure, where the pultrusion (i.e. longitudinal fibre) direction of the box profiles were placed perpendicular to the pultrusion direction of the flat plates. This orientation improves structural performance by enhancing the junction between the box profiles and face plates to prevent premature cracking. In this paper, three different span lengths were investigated: a 4.5 m continuous span and 9 m and 6 m single spans. Composite action of the connections and the bidirectional deck was studied, along with shear lag under both positive and negative bending.
