高強度鋼用の複半月テーパ充填ボルト接合法の開発 On Fastener using Half Moon Shaped Bolt for High-Strength Steel Member(Part 1 Concept of Half Moon Shaped Bolt) 玉井, 宏章 タマイ, ヒロユキ 高松, 隆夫 タカマツ, タカオ 山西, 央朗 ヤマニシ, テルアキ Tamai, Hiroyuki Takamatsu, Takao Yamanishi, Teruaki H-SA700 High strength steel Bearing High strength bolt application/pdf The authors have been involved in the research project to develop members of built-up structures using high-strength steel of 780N/mm2 that are utilized in buildings which can withstand a severe earthquake (JMA seismic intensity of 7) and enables rapid functional recovery. We propose weld-free built-up structural members that have the cross section of two high-strength steel channels stitched together with bolts. Joints for high-strength members are required a lot of bolts by use of ordinary friction bolts. Joint length of the friction bolts is so longer as to avoid a practical structural design such as high rise buildings. Hence, the authors present a new fastener for high-strength steel members. A new fastener is half moon shaped bearing bolt. The fastener has high strength due to bearing bolts. And it has no slip phenomena, so high stiffness of fastener is promised. This paper shows the concept and capabilities of presented bolts. 広島工業大学 2011 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/882 40018724475 AA11599110 13469975 広島工業大学紀要. 研究編 45 127 136 https://it-hiroshima.repo.nii.ac.jp/record/882/files/kenkyuhen45127.pdf application/pdf 13.5 MB 2023-03-30
