The strengthening method with bonding Carbon Fiber Reinforced Polymer (CFRP) strips has been merely applied to steel structures despite of many applications on concrete structures. In order to obtain useful information for application of bonded CFRP strips on steel structures, tensile tests on steel plates strengthened with CFRP strips were conducted. In the current study, the influence of the thickness of adherends and the number of layers of CFRP strips was investigated. The test results indicated that the reduction of tensile strain at the neutral axis in the steel plate can be estimated by a simple equation although a moment was existed in the specimen due to the CFRP strips bonded only on one side of the steel
