The aim of this work is the study of the load bearing capacity of two solid timber beams mechanically jointed by fully threaded timber screws. The obtained results are compared with the load bearing capacity of a glulam beam with the same dimensions. A four-point bending test according to LVS EN 408+A1:2012 points 9, 10 and 19 is performed to determine the modulus of elasticity and the bending strength. The test results are compared to analytical calculations according to Eurocode 5 requirements. The aim is achieved by comparing the characteristics of both beams. The main difference between mechanically jointed solid timber beam and a glulam beam is that joint of the beams reduces the modulus of elasticity while still providing good bending strength.
