Laminated wood - Techinical sheet The load-bearing structure in Laminated Wood comprises two or three zipped arches, suitably curved according to the outline project in conifer wood GL28c. The arches are made from milled layers of cross laminated joints, glued with suitable products as specified in the gluing Connection between the arches made this way is censure by special struts still made from laminated conifer wood GL24h. Connection is made through steel plates and high resistance nails or bolts, depending on the necessity and plan's specifications. The external spans are normally fitted with steel struts capable of discharging the arches' orthogonal push Here follow the resistance guide tables to use in structural calculations, the reference standards and the combinations of load actions.

Primary structure characterized by two or three zipped arches and secondary structure made up of struts. Presence of steel tie rods. The STATIC analysis made is of the elastic-linear type. The STRUCTURE'S SEISMIC analysis is of the dynamic-modal type. The project is checked using the State of Limit method. Combinazione delle azioni {vd.

The biaxial pre-tension of the covering's fabric membrane is taken into due consideration which, even though it's not expected by the standards in force, exercises a constant load on the arch. The load-bearing structure is made up from prefabricated, glued laminated wood elements. Tensions and deformations are assumed on the basis of calculations and refer to a wood and glue quality as specified in table 6 of the DIN 1052 standard. The layers comprising the glued elements are in conifer wood (spruce) GL28c for the curved parts and GL24h for the straight parts, based on the directives of the standards...

The covering membrane is made up from a highly resistant synthetic fibre POLYESTER and waterproofed with a PVC coating on both faces. The membrane used for covering laminated wood structures is in polyester fibre, synthetic and rot proof. The thread it is made from is Dtex 1.500 and is equal in weight to a reel of 10,000 mt. of thread. The membrane's mechanical characteristics are chosen on the basis of the accidental overloads it is subjected to, and these are done at the planning stage. The available materials are subdivided into 6 types having different characteristics and shown on the relative...
