Laminated glulam is a new engineering wood material produced in response to changes in forest resource structure and the development of modern building structures. This product not only retains some of the excellent characteristics of natural solid wood sawn timber, but also overcomes the uneven material and size of natural wood. Limitation, drying and difficulty in anti-corrosion treatment.
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 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.
