摘要:
为研究胶合木粘钢连接的顺纹拉拔力学性能,开展了27个胶合木粘钢试件的试验研究,主要变化参数为锚固长度和钢板上的开孔密度或孔间距。对比分析了破坏形态与破坏机制、荷载-滑移曲线和等效黏结强度等结构性能。试验结果表明:锚固长度和钢板上的开孔密度是影响胶合木粘钢承载力的主要因素; 粘钢试件破坏模式主要有钢板拉断、钢板屈服、木材剪切破坏和钢板-胶层界面破坏; 通过对粘钢试件的合理设计,能够避免发生木材剪切破坏和钢板-胶层界面破坏等脆性破坏,实现具有大承载力和高延性特性的延性破坏形式。最后,基于试验结果提出胶合木粘钢连接的破坏模式判定方法,并给出了设计建议。
Abstract:
This paper described the experiments 27 steel plate bonded in glulam specimens to investigate the pull-out strength of steel plate bonded in glulam parallel to the grain.Influencing parameters such as anchorage length and hole spacing of the bonded-in steel plate were studied consideration.The failure modes,failure mechanics,load-slip curves and equivalent bond shear strength of specimens were analyzed.The test results showed that the main influencing factors on the load bearing capacity were the anchorage length and hole spacing.The failure modes included the steel plate fracture,the steel plate yielding,wood shear failure and steel-resin interfacial failure.Through the rational design of the specimens,the brittle failure such as wood shear failure and steel-resin interfacial failure can be avoided,which resulted in ductile failure with high load bearing capacity and good ductility.Finally,based on the test results,the determination method and design recommendations were presented.
