Modelling of Non-metallic Timber Connections at Elevated Temperatures

摘要

Models estimating the slip modulus and the load capacity, including temperature dependent effects, of non-metallic timber connections are presented. Previous studies, including the work of Thomson, have shown that 'Glass Fibre Reinforced Polymer' (GFRP) rods are suitable connectors for timber and that 'Densified Veneer Wood' (DVW) functions effectively as a flitch plate material. Thomson's model predicting the slip modulus of the connection with GFRP rods and DVW plates is revised in this paper. The revised model is used to predict the slip modulus and the failure load at room temperature and elevated temperatures. The latter is achieved by predicting local temperatures in the connection and taking corresponding reduced material properties into account.
