Adhesive Fatigue Test on Rehabilitated Steel Beam Bonding CFRP Plates Part 1 Preliminary Adhesive Fatigue Test

摘要

The authors have developed a tensile force strengthening method using bonded carbon fiber reinforced plastic (CFRP) plate to enhance the life of existing building. Inthis study, performs dynamic fatigue tests on rehabilitated steel beam bonding CFRP plates to reveal fatigue properties of the adhesive and examines fatigue fracture properties of adhesive on cyclic loading. In previous paper, calculated stress distribution of adhesive layer, and its showed validity. Also, it examined fatigue limit of adhesive on the basis of the modified Goodman law. In this paper, reports performing preliminary fagigue test for performing adhesive fatigue test to reveal the fatigue properties of adhesive. The result showed that shear yield limit and reversed fatigue limit was greater than assumed value.
