Sažetak
The paper presents experimental tests and finite element analysis of several glulam beams made of different wood species. The glulam beams are tested by means of 3- point bending tests on short samples (Figure 1). Experimental tests include measurements of applied forces, strains and displacements. The displacements and strains are obtained using a novel photogrammetric approach [1]. In this work we present details of the test specimens, test set- up, procedures and results of the bending tests. The current research aims to determine the behaviour of glulam wood and to obtain elastic properties for each specimen. Particular attention is given to the accurate analysis of the type and mechanisms of failure [2]. The results of the bending tests have shown that delamination of the glulam beams causes a decrease in their stiffness and leads to bending failure of the individual lamella. Finally, comparison is made between photogrammetric and linear variable differential transducer deflection measurements. The mechanical properties obtained from the experiments are validated with the results from FEM analysis.
