Abstract

The ability to provide the joint versatility for pultruded fibre reinforced polymer (PFRP) in civil structures industry is crucial for its application demands. Bolted joint is extensively used in the industry due to low cost and ease of assembly. However, this jointing method can compromise the PFRP strength at the joint due to poor quality of drilling techniques, accuracy of hole size and threaded bolt. In this study, the main objective is to investigate the effect of threaded bolt on the strength of bolted joints in pultruded fibre reinforced polymer. Double lap joint configuration was used on both longitudinal and transverse laminates and tested to failure (in tension) in accordance with ASTM D5961. The test specimens failed in shear-out (heavily crushed) mode and net-tension mode for longitudinal and transverse laminates, respectively. A significant joint capacity reduction was observed on the threaded samples due to unevenness of the contact surface. The load-displacement curve shows the slope with several knees after the first drop, which may indicate some damping effects and unstable development of internal damage.
