Abstract : This paper presents the issues necessary to develop rational structural intervention methods, especially external bonding, overlaying and jacketing in terms of design, construction and maintenance of structures with structural intervention. Some solutions for those issues are introduced in this paper, which include (1) Application of new materials, (2) General design approach for shear strength and ultimate deformation of linear members with reinforcing steel/new materials, (3) General design approach for shear strength of planner members,(4) General design approach for various debonding failure modes, (5) Effects of interface properties on debonding, (6) Design for cracks, and (7) Long-term performance prediction of interface property. This paper also introduces briefly the recent development of international standards onstructural intervention, which show a model for national standards. Through the internationalization of standards, we can develop rational framework of maintenance, which includes intervention, and common terminology to avoid unnecessary confusion for maintenance activities on site. At the end of the paper the remaining tasks are summarized.
