摘要

The experimental investigation on the tensile strength of bolt joints in pultruded GFRP(Glass Fiber Reinforced Plastics) members used for pedestrian bridges are described in this paper. Adding biased cloth layer into the members was effective in improving the tensile strength of bolt joints. Also, taking longer edge distance for bolt holes was effective and gave higher tensile strength. The fracture modes of joints using large diameter bolts were shear failure for all types of specimen.
