Rotational Behavior of Innovative Glued Laminated Bamboo Beam-to-Column Connections Using External Steel Plates and Self-Tapping Screws
针对胶合竹材不易预开槽和预开孔以及节点转动时竹材易发生横纹劈裂的问题,研究了新型外包钢板-自攻螺钉连接节点的转动性能.对T形外包钢板-自攻螺钉连接节点和双L形外包钢板-自攻螺钉连接节点共5个试件进行了单调加载试验,分析了节点的破坏模式、初始刚度、极限承载力、变形能力和延性系数.试验发现,T形外包钢板-自攻螺钉连接节点相较双L形外包钢板-自攻螺钉连接节点,各项受力性能参数均较优.布置直径小但数量多的自攻螺钉时,节点(T8X8-M)的破坏表现为钢板和…查看全部>>
In order to solve the difficulties of slotting and perforating of laminated bamboo,and the problem of bamboo splitting when the beam-to-column connections were rotated,the rotational behavior of innovative laminated bamboo beam-to-column connections using side steel plates and self-tapping screws were studied.Two types of connections were designed,and a monotonic loading test was conducted on 5 specimens,including T-shaped extended end plate connections with…查看全部>>
