Fabrication and testing of cuff connections for GFRP box sections
A new type of connection between beams and columns has been designed and fabricated specifically for use with GFRP (glass fiber reinforced plastic) pultruded box members. The following sections explain in detail the procedures and materials used for manufacturing the GFRP epoxy cuff connection using BARTM (vacuum assisted resin transfer). The specimens fabricated were then tested, with their performance judged by stiffness and ultimate strength measurements. Monolithic cuff connections fabricated using the procedure described herein were easily attached to GFRP pultruded box members to create simple beam-cuff-column frames, using standard construction techniques for pultruded materials (epoxy adhesive bonding) that can be practically implemented in the field. Two beam-cuff-column frames were mechanically tested to failure under reverse-cyclic static loading. Test results indicated that these beam-cuff-column frames had higher overall and connection elastic stiffness than previous generation frames constructed with connections consisting of combinations of angles, bolts, and epoxy.
