摘要：
In this study, in an attempt to examine the effects of GFRP on the improvement of the fatigue crack initiation life Ni and fatigue crack propagation life Np, fatigue tests were conducted for out-of-plane gusset welded joints to which GFRP were attached using the primer. The effectiveness of GFRP for reducing the stress at the toe of round weld was also investigated analytically. The effectiveness of GFRP for controlling the fatigue crack propagation rate was also considered from a viewpoint of fracture mechanics
