Glulam columns and beams are structural wood engineering products, which are formed by gluing the timbers together in parallel with the help of glue and are widely used in the construction of wood structures. Steel plates, aluminum plates or simply wooden parts are commonly used at the joints of wood structures. Steel elements that are often used as joints can corrode and also aluminum plates are not resistant to heat. For this reason, the use of non-metallic fasteners is one of the topics that have been emphasized recently. In this study, it is aimed to strengthen the joints of glulam column-beam connection with carbon fiber reinforced polymer. For this purpose, 2 column-beam joint samples were produced from each connection type using WV90080 and ALUMIDI 160, WV90110 and ALUMIDI 200 connection elements. One of the samples produced in each connection element was wrapped, and the other was not. The column-beam joint samples produced were subjected to the load–displacement test within the framework of the experiment. It was determined that the load bearing capacity, energy dissipation capacity and stiffness values of the samples whose column-beam connection area was strengthened. It has been specified that reinforcement with carbon-based FRP fabric increases the strength and durability of the column-beam connection area.

纤维增强聚合物复合材料增强胶合木柱梁节点旋转性能的实验研究

胶合木柱和梁是木材的结构工程产品,通过在胶水的帮助下将木材平行粘合在一起而形成,并广泛用于木结构建筑中。钢板,铝板或简单的木制零件通常用于木结构的连接处。经常用作接头的钢元件会腐蚀,并且铝板也不耐热。因此,非金属紧固件的使用是最近强调的主题之一。在这项研究中,目的是加强与碳纤维增强聚合物的胶合木柱-梁连接的接头。为此,使用WV90080和ALUMIDI 160,WV90110和ALUMIDI 200连接元件从每种连接类型生产了2个柱梁接头样品。每个连接元件中产生的一个样品被包装,而另一个则没有。在实验的框架内,对所产生的柱梁接头样品进行了载荷-位移测试。确定了柱梁连接面积得到加强的样品的承载能力,能量耗散能力和刚度值。已经指定,使用碳基FRP织物进行增强可以提高柱梁连接区域的强度和耐用性。柱梁连接面积得到加强的样品的耗能能力和刚度值。已经指定,使用碳基FRP织物进行增强可以提高柱梁连接区域的强度和耐用性。柱梁连接面积得到加强的样品的耗能能力和刚度值。已经指定,使用碳基FRP织物进行增强可以提高柱梁连接区域的强度和耐用性。
