Analytical Study on Flexural Behaviour of Glued Laminated Timber

摘要

This study determines analytically the flexural properties of glued laminated timber beam (glulam) with different thickness of lamina and jointed lamina; it was compared to solid beam. This research used Rubber wood (Hevea brasiliensis). Glulam beam was divided into three groups based on the thickness of lamina, 20 mm, 15 mm and 10 mm respectively. Solid beam was also modelled besides glulam beam. Jointed wood with finger outside maximum moment zone in the bottom lamina was also modelled. Solid wood and laminated wood of rubber wood species was modelled and analysed in ANSYS 14.5.Then modelling of finger joint was done in Computer Aided Three-dimensional Interactive Application (CATIA) and analysed in ANSYS. The result was compared with the available experimental result. The results obtained show that the comparison of flexural properties between solid wood and horizontally glulam wood have no significant difference. Lamina thickness does not make any statistically significant difference in the flexural properties.
