项目摘要
Inserted type fasteners, such as a lagscrewbolt and a steel rod glued into timber, are proposed as one of the fasteners for middle and large scale timber buildings and timber portal frames. The moment resisting joint with lagscrewbolts etc. shows good mechanical performance and aesthetic. However, the beam and column joints rarely showed a brittle shear failure in the panel zone of the column in previous studies. Therefore, in order to prevent the failure and improve the joint properties, a cross embedded joint with lagscrewbolts was developed. And the joint reinforced with long screws was also developed with considering simple timber processing.The cross embedded joint with lagscrewbolts showed a good ductile performance and a good reinforcing effect against the shear failure in a column and the brittle pull-out failure. And the joint with long screws also shows a good reinforcing performance.
建议将插入的类型紧固件(例如落后螺栓和粘在木材中的钢棒)作为中层和大型木材建筑物和木材门户框架的紧固件之一。用Lagscrewbolts等抵抗接头等的力矩表现出良好的机械性能和美学。然而,在先前的研究中,梁和柱接头很少显示圆柱面板区域的脆性剪切故障。因此,为了防止故障并改善关节特性,开发了带有落叶螺栓的交叉嵌入关节。并且还考虑了简单的木材加工,还开发了用长螺钉加固的接头。带有落叶螺栓的交叉嵌入接头表现出良好的延展性性能,并且对圆柱中的剪切故障和脆性拉出失败具有良好的增强作用。长螺钉的关节还显示出良好的增强性能。
