METHOD FOR MAINTAINING STEEL STRUCTURE PREVENTIVELY

摘要

PROBLEM TO BE SOLVED: To provide a new system for maintaining a steel structure preventively to prevent a structurally discontinuous part of the steel structure from being cracked owing to repetitive stress. SOLUTION: This method for maintaining the steel structure preventively comprises a step of applying a primer to the structurally discontinuous part caused by a weld joint of the steel structure to prevent the structurally discontinuous part from being cracked owing to repetitive stress. The steel structure is preferably a structural part of a bridge. COPYRIGHT: (C)2006,JPO&NCIPI
