Investigation of glued in bars strength and deformability indexes within framework of research of wood reinforcement with cable reinforcement

Abstract

Abstract The increasing demand for the low-height housing construction frame technology keeps current the issue of saving timber in building construction. The method of reinforcing beams with reinforcing steel is a promising direction of research in the field of ensuring the gain in strength and the cost indexes reduction of structures. In 2017 as a graduate student of the Department of building structures of VlSU Koscheev A.A. proposed for the investigation a new type of reinforcing wooden beams by the steel cable reinforcement in solid wood along the original curvilinear trajectory. As of today, a number of numerical investigations in this area was carried out and the process of the full-scale experimental investigations was launched. This research article is devoted to the first cycle of the experimental analysis in this area: investigation of the influence of the steel wire rope strength characteristics on the behaviour of the adhesive interlayer of the epoxy composition when conducting tensile tests – pulling out a straight bar from the solid wood. On the basis of the data obtained, conclusions on the applicability of the rope reinforcement in solid wood constructions were drawn and the main directions for further research were determined.
