It has only been in the recent decade that fibre reinforced polymers (FRP) are being utilized in civil structures through use of pultruded sections. The joining and connection of these members are critical for the integrity of the structures. Due to the orthotropic nature of FRP and the vast number of pultrusion manufacturers in the industry the development of standards for connections has been restricted to only guidelines such as the EUROCOMP handbook. In the last decade construction using FRP pultrusion has become more widely used and there has been more research to investigate the failure of connections by mostly experimental testing. Previous research and the current guidelines both from EUROCOMP and manufacturers show variations in recommended and minimum geometry associated with joint design with FRP pultruded sections.

This research will study the stress behaviour of simplified lap-joints with a single and multi-bolt configuration with particular attention to the critical failure planes associated with net-tension, bearing and shear-out failure modes. A finite element analysis and theoretical study into geometric parameter changes will also be investigated to establish differences between previous research conducted and the current guidelines set out in the pultrusion industry. There has been little research conducted in multi-bolt (single row) connections so this will be incorporated into the study in an attempt to show any irregularities and differences when compared to single-bolt connections. Based on results of the FEA conclusions will be made and findings presented with a focus on suggested geometry for FRP
tension joints.
