摘要

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.
