REUSE SYSTEM OF BUILDING STEEL STRUCTURES

Abstract

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. The reuse system mainly aims at reusing building steel structures that have already constructed. On the other hand, the sustainable building structure aims at reusing new building steel structures in the future. This structure is one form of a damage-controlled structure. Clearly separating the main structure from seismic energy absorption members keeps the main frame within the elastic range, and the seismic energy absorption members can collectively absorb the seismic energy force. The continued use of the main structure is possible by replacing only earthquake-damaged braces where necessary; reusing structural members is also possible.In this paper, the authors verify that the sustainable building structure is suitable for reusing structural members through trial construction. Then, easiness of erection and dismantling of sustainable building structure is evaluated.
