内嵌多块钢板销式连接木结构节点承载力的计算与设计方法

随着技术的发展,现代木结构开始向大跨、多层方向发展,在荷载作用下连接节点处往往会产生较大的内力,而内嵌多块钢板销式连接节点具有较高的承载力且破坏具有较好的延性,越来越广泛地应用于现代木结构设计中.介绍了内嵌3块钢板销式连接节点的破坏模式,根据Johansen屈服理论推导了各种破坏模式下其承载力计算公式,并简要地介绍了实际工程中连接节点在弯矩M、剪力V共同作用下的设计方法,对实际木结构工程中该类连接节点的设计具有一定的参考价值.

Calculation and Design Method of Load-Carrying Capacity of Dowel-Type Timber Connections with Multiple Slotted-in Steel Plates

With the development of modern technology,modern timber structures begin to develop in the direction of large span and space.Usually these connections have a greater inner force,while the dowel-type timber connections with the multiple slotted-in steel plates have a higher load-carrying capacity and their destruction has a better ductility,so this type of connection has been widely used in modern timber structure designs.The failure mode of the connection is introduced and the formula of load capacity of the connection deduced based on Johansen yield theory under various failure modes.This design method of the connection subjected to an applied moment M and shear V force is presented in light with the actual project,which has a certain reference for the connection design in the actual timber structure engineering.
