Abstract

Highlights: Timber connections represent a reduction of continuity and strength. An extensive experimental campaign is presented with Maritime pine and Iroko. Iroko presents higher embedment strength for parallel to the grain direction. Maritime pine and Iroko have similar performance for self-tapping screwed connections. Both species comply with the requirements from Eurocode 5. Abstract: In this study, screwed connections were experimentally evaluated, checking the plausibility of Eurocode 5 for two selected wood species, Iroko ( Milícia excelsa ) and Maritime pine ( Pinus pinaster ). Single shear screwed connections, considering self-tapping screws, were tested and the experimental campaign aimed at evaluating various mechanisms of resistance suggested by Eurocode 5 for this typology of connection, including axial withdrawal capacity of the screw, pull through parameter for screws, and local embedment of wood. The experimental results evidenced that the analyzed connection system had similar results with either wood species. The results were consistent with the calculation through Eurocode 5.
