Summary
Wood has long been in demand as a competent building material due to its beauty, economy, and ease of construction. Excellent material properties are exhibited by a number of new engineered wood products such as gluedlaminated (Glulam) and cross-laminated timbers (CLT). New experimental data on the structural behaviour of CLT-toGlulam composite-section beams is presented in this paper. Four large-scale test assemblies composed of two different engineered wood sections were tested. Beam composite sections were built of a top flange part made of a cross-laminated timber slab and a web part made of a Glulam rectangular section. The two parts forming each beam section were connected together using 5/16 self-tapping screws in order to create composite action. Results from this research showed that reducing the spacing distance between screws considerably increased the flexural stiffness of the CLT-to-Glulam composite beams.
