TY  - JOUR
AB  - An analytical model that can describe the load-slip response of cold-formed steel-to-timberconnections, based on three components: timber embedment, screw bending and the axial pullthrough, is presented. The model takes into consideration the screw inclination and the damageto the timber caused during the screw drilling process. The model was validated againstavailable push-out test results, where it was shown that the model can accurately describe theultimate load, the slip at ultimate load, and the two slip moduli, ks and ks,m, with mean modelto-test ratios of 1.01, 1.03, 1.09 and 0.96, respectively. The observed failure modes were alsoaccurately predicted. Comparisons between the test data and the predictions of the EN 1995-1-1 design expressions showed that the Eurocode underestimated the ultimate loads by around50% on average and overestimated the slip moduli by around 500% on average; the proposedmodel therefore offers a significant improvement over current design provisions.
