Cyclic Tests of Joints of Glued Wooden Structures

Abstract

Abstract The use of large-span structures made of glued wood in countries with large timber reserves in Finland, Sweden, Norway, Russia, the USA and Canada has shown that this can be quite interesting and expressive from the architectural position of the building. Sports facilities, sports and sports facilities, sports facilities, sports and cultural facilities. The practice of building bridges made of glued wood in these countries shows that they have been in operation for decades without additional operating costs. Glued wood in modern conditions, when productive flame retardants are used that protect it from fire, antiseptics from possible decay expand the scope of such structures. One of the important obstacles to the limiting applications of large-span glued wooden structures is the complexity of the solution nodes. Bearing structures experience difficulties when exposed to static and cyclic loads. Cyclic loads can be caused by wind loads, production equipment, traffic, and seismic processes. Reinforcement in wood, reinforcement and reinforcement under load. Wood and metal are resistant to cyclic loads. Studies will be conducted at the border of the elements to be glued. This article presents the results of tests for the effects of static and cyclic loads on reinforcement from a 14 mm reinforcing bar of class A5 on FRF-50T along natural-sized glued wood fibers. Certain coefficients of the endurance of the compound when exposed to cyclic loads with two load asymmetry coefficients p = 0.5 and p = 0.2.
