Abstract: PURPOSE: A reinforcement sheet attached to a steel structure is provided to control a structure failure and disperse the stress because adhesion performance can be improved in case of attaching a reinforcement sheet to a steel structure. CONSTITUTION: A reinforcement sheet attached to a steel structure(100) comprises a reinforcement portion(110), an attachment portion(120), and a stress reduction portion(130). The reinforcement portion is attached along a longitudinal direction of a steel structure. An adhesion is improved by enlarging a contact area between the steel structure and attachment portion. The stress reduction portion prevents a stress concentration actuating on an end part where the steel structure is contacted.
