Steel structural beam anti-fatigue reinforcing method
The invention discloses a steel structural beam anti-fatigue reinforcing method; a fatigue sensitive area of the steel structural beam is bonded with carbon fiber clothes so as to realize anti-fatigue reinforcement of the steel structural beam, thus fundamentally improving fatigue life of the steel structural beam; for instance, a bonding area of the carbon fiber clothes in the fatigue sensitive area below a steel structural beam neutral axis is enlarged so as to increase fatigue crack expansion restriction capability, and to increase reinforcing effect of the carbon fiber clothes close to stiffening ribs; in addition, the anti-fatigue reinforcing method can prevent carbon fiber clothes from being bonded in non-fatigue sensitive areas of the steel structural beam, thus preventing material waste; i.e., the steel structural beam anti-fatigue reinforcing method can use less material consumption to reach the reinforcing effect as possible, and is not high in enforcement difficulty.
