STRUCTURAL CHARACTERISTICS OF FORMER HIDAKA-TOWN-OFFICE BEFORE RENOVATION Investigating structural characteristics and decay deterioration of wooden members through blueprint analysis and partial disassembly

Abstract

This paper examines the structural characteristics of the Former Hidaka-Town-Office, located in Toyooka-city, which was constructed in 1935, as well as the corrosion deterioration of its wooden members. A comparison with previous research reveals that the structure aligns well with the advanced design of Western-style wooden buildings from the early Showa era. The construction of the roof trusses is mechanically rational, but the joints connecting beams and braces may be fragile. Most of the corrosion deterioration in the wooden members was found within the outer walls, while other parts of the building remain in good condition without significant deterioration.
