ABSTRACT

The objective of this study was to evaluate tensile properties of utgulisanji connection. The utgulisanji connection is a traditional wood-to-wood connection used in wood-frame buildings in Korea. Different sizes (120 × 120, 180 × 180, 180 × 240, 240 × 240 mm²) of glulam beam at 2.4 m length made from Larix kaempferi and Pinus koraiensis were used to determine the tensile properties of utgulisanji connection. Most failure occurred at the re-entrant corner of utgulisanji connections. Different elasto-plastic behaviors of utgulisanji connection made from different species under tension indicated that tensile properties of utgulisanji connection could not be determined by specific gravity, but by a combination of manufacturing parameters with properties of materials. Initial stiffness, yield load, and maximum load of utgulisanji connections determined using three different methods increased with the size of member, whereas the yield displacement showed an inconsistent trend with the size of member.

抽象的

这项研究的目的是评估utgulisanji连接的拉伸性能。utgulisanji连接是韩国木结构建筑中使用的传统木-木连接。不同尺寸（120×120、180×180、180×240、240×240毫米²用落叶松和红松制成的长度为2.4 m的胶合梁确定utgulisanji连接的拉伸性能。大多数故障发生在utgulisanji连接的重入角。由不同物种在拉伸下形成的utgulisanji连接的不同弹塑性行为表明，utgulisanji连接的拉伸性能不能由比重决定，而只能由制造参数与材料性能共同决定。使用三种不同方法确定的utgulisanji连接的初始刚度，屈服载荷和最大载荷随着构件尺寸的增加而增加，而屈服位移显示出与构件尺寸不一致的趋势。
