ラグスクリューボルトと特殊金物を用いた木質ラーメン構造の桂-梁接合部に関する研究

摘要

A lagscrewbolt was developed by third author as a simple and economical moment-resisting connector for glulam constructions. In previous reports, the theory on pull-out capability were developed and verified experimentally. In this report, a beam-column joint using lagscrewbolts were developed, and the design methods were proposed. The joints, composed by a special nut, a steel plate and a special steel connector similar to Japanese traditional wooden connector "Chigiri", were developed to assemble each member simply on-site and prevent from a brittle failure. As a result, the joint system showed a good performance, and it was agreed with an analytical result.%近年，校舎などの中規模施設，また住宅においても開口部を 広く設けた建物を木造で建築したいとの要望が多くなっている。 これらの要望に応じるために数多くの木質ラーメン構造に関す ろ研究が行われている。
