Reuse Dismantling and Performance Evaluation of Reusable Members

The reuse system mentioned in this paper is an overall system for realizing a reuse business in a cyclic process of design, fabrication, construction, maintenance, dismantling, and storage. Here, we propose reuse dismantling to minimize the damage to structural members for future reuse, and performance evaluation of reusable members focusing on rolled H-sections. Structural members obtained by reuse dismantling or conventional demolition are evaluated by visual inspection, dimensional inspection, mechanical property tests, chemical component tests, and degradation inspection. For structural members to circulate as reusable members in the existing distribution system, two industries are needed: one responsible for production and product supply, which has already been established, and the other facilitating disposal, recycling, and reusing of the products resulting from the former. The authors define the former as the arterial industry, and the latter, as the venous industry, showing the size and importance of both industries.
