NEW DESIGN CONCEPTS FOR STRUCTURAL TIMBER CONNECTIONS

摘要

The experimental study on glassfibre reinforced and densified timber joints has shown that the load carrying capacity could be increased up to two times. Apart from the ultimate load, stiffness and ductility are improved considerably so that construction elements and parts could be prevented from sudden failure. The structural use of densified wood arise questions about the bonding to wood and glassfibre fabrics. Particularly, the connection of densified and undensified boards which was done in this study by means of finger joints present a weak point and must be improved. In order to fully benefit from new technical textiles, more especially from those having an optimal orientation regarding the stress state of the construction element, fundamentals in mechanics of the wood-textile-composite are required as a prerequisite.
