This study presents a newly developed timber–glass point connection intended to strengthen existing timber elements in a reversible and visually unobtrusive manner. The new connection consists of an aluminium insertion, two-component structural bonding epoxy resin adhesive, and self-tapping screws. The connection offers the possibility of easy attachment and detachment of the glass element from the strengthened timber element. Seven timber–glass specimens were constructed to perform an experimental investigation of the shear load-bearing capacity and load-slip behaviour of the connection. The aluminium insertion is bonded to a tempered glass strip with a hole and is screwed to the spruce timber block. The timber–glass connection preparation process is thoroughly presented. A special testing apparatus was developed to perform the experiments on a hydraulic universal testing machine. The experimental results are evaluated using analytical expressions and a finite-element simulation. The average connection load-bearing capacity obtained from the experiments of the analysed specimen was 13.31 kN, and the average slip modulus was 20.48 kN/mm. All connections failed on account of self-tapping screw failure, whereas the tempered glass strips remained undamaged.

木材-玻璃复合结构的新型复合连接

这项研究提出了一种新开发的木材-玻璃点连接，旨在以可逆的且在视觉上不引人注目的方式来增强现有的木材元素。新的连接包括铝插入件，两组分结构粘接环氧树脂胶和自攻螺钉。该连接提供了容易将玻璃元件与加强的木材元件附接和分离的可能性。构造了七个木材-玻璃试样，以进行连接的剪切承载力和荷载滑移行为的实验研究。铝制插入件粘结到带孔的钢化玻璃条上，并拧入云杉木材块。木材-玻璃连接的准备过程已全面介绍。开发了一种特殊的测试设备以在液压万能测试机上进行实验。使用解析表达式和有限元模拟对实验结果进行评估。由分析样品的实验获得的平均连接承载能力为13.31 kN，平均滑动模量为20.48 kN / mm。由于自攻螺钉故障，所有连接均失败，而回火的玻璃条仍未损坏。
