Abstract:
1. A method for reinforcing a structure comprising: disposing a high-ductility material on an outer circumferential surface of a member of the structure to restrain expansion of apparent volume accompanying rupture of the member, to thereby control rupture of the member; winding the high-ductility material by a single turn at a winding start end of the member; winding the high-ductility material spirally while a number of overlap turns is sequentially increased until a predetermined maximum number of overlap turns is reached; winding the high-ductility material spirally while the maximum number of overlap turns is maintained along a predetermined length of member; and winding the high-ductility material spirally while the number of overlap turns is sequentially decreased such that the high-ductility material is wound by a single turn at a winding termination end of the member.
