In recent years, the Glass Fiber Reinforced Polymer Plastic (GFRP) structural shapes are available in civil engineering applications. Among many manufacturing techniques used for GFRP structural shapes, pultrusion process is one of the most widely used techniques to produce the structural members in civil engineering applications. This study was focused on the mechanical behavior of singly bolted lap-joint connection with various hole clearances (tight-fit: 0.5mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm) in Pultruded GFRP structural members. The specimens with single bolt-hole have been tasted in tension under bolt-loading conditions. The failed specimens were examined for their failure load and fracture patterns with respect to the various hole clearances.
