The glulam structure is a modern wood structure system in which the main structural component materials are glulam. In recent years, many glulam structures have appeared and unique shape.
Due to the small elastic modulus of the wood itself and the poor initial flexural rigidity of the wood beam-column joints, the pure glulam frame structure system often has insufficient lateral resistance, so the wood frame support structure and the wood frame shear wall structure are mostly used.
The boards or small squares with parallel wood grains are firstly terminated or edged in the length or width direction to form laminates, and then laminated and glued wood materials in the thickness direction. However, structural plywood has higher quality requirements than general decoration plywood, and must have specific quality standards.
The strength and durability of glulam structures depend to a large extent on the quality of the glue. To be designed according to special regulations. Therefore, in the design and manufacture, special technical requirements should be put forward for the selection of glue, the splicing structure of wood and the conditions of gluing process.
Due to its high load capacity and low weight, glulam allows you to cover large areas of components. It can cover structural sections up to 100 meters long without intermediate supports. In a fire, structures made of glue-laminated wood are safer than unprotected steel structures.
