摘　　要：以花旗松CLT和自攻螺钉为材料,探究自攻螺钉以不同的角度,钉入CLT中以及是否插入CLT拼接缝对传递議和破坏模式的影响,分析轴向承载的强度、刚度、延性变化规律,对我国木结构规范中的连接设计进一步完善,提供试验数据和理论依据。为建立“CLT-STS”模型提供理论参考。In this paper,douglas fir CLT and self-tapping screws were used as research materials,explore the impact of self-tapping screws on CLT at different angles,and whether to insert CLT splicing joints into the transmission mechanism and failure mode,analyze the changes in axial load strength,stiffness and ductility,and design the connection method to be further improved in the Chinese wood structure code and provide experimental data and theoretical basis.Provide a theoretical reference for the establishment of the"CLT-STS"model in my country.

关 键 词：钉入角度 自攻螺钉 正交胶合木 握钉力
