Resumen
Descripción
The aim of this study was to investigate the effect of thin wood part on the load-carrying capacity of inclined self-tapping screw. Two components of load-carrying capacity (withdrawal and shear capacity) were tested to examine the effect of thin wood part. Combined load-carrying capacity of inclined screw loaded upward was also tested and compared with the prediction value from EN 1995-1-1. Screws were installed in Glued-laminated timber (GLT) and two different dimensions of screws (Ø8.0 × 100 mm, Ø6.5 × 65 mm) were selected. As a result, thin wood part affected relatively little on the withdrawal capacity, compared to the shear capacity. EN showed conservative result in combined load-carrying capacity, even though shear capacity of inclined screw declined due to thin wood part.
