内嵌钢板销式木连接抗火性能研究进展

A Review of Fire Resistance of Dowel-type Connections with Slotted-in Steel Plates

在已有的内嵌钢板销式木连接相关文献及规范的基础上,总结了销式木连接在常温下及受火时的破坏模式与破坏机理以及影响内嵌钢板销式木连接耐火性能的因素;这些因素包括荷载水平、木材几何构造、紧固件数量与直径以及紧固件类型。本文还通过比较耐火极限理论计算值与试验值,对几种耐火极限计算方法进行了评述。

Based on the relevant published papers and codes covering steel-to-timber connections, a review of the failure modes and failure mechanism of steel-to-timber connections at ambient temperature and exposed to fire was given. The parameters influencing fire performance of connections, including load ratio, geometric configuration of timber, the number and diameter of fasteners and the type of fasteners were also discussed in this paper. Finally, several numerical calculation methods of fire resistance of timber connections were evaluated, through making a comparison between the theoretical values and experimental results.
