Abstract
Depending on physical and geometrical boundary conditions, withdrawal and/or steel tensile failure govern the structural design of axially loaded self-tapping screws. Therefore needed parameters such as the withdrawal strength fax or the steel tensile capacity ftens are commonly determined by tests and given in technical approvals and standards.
Consequently, it is of major importance to apply a test configuration and procedure guaranteeing a general validity for the broad bandwidth of screw applications. Due to the fact that the mechanical steel behaviour of modern timber screws (i) is comparable with those of similar steel products and (ii) has a typically low dispersion, we concentrate in this paper on
effects influencing the withdrawal strength representing the composite behaviour timber-screw. Thus, we show and discuss results of an experimental campaign, aiming to investigate the influence of different load path and supporting conditions as well as of varying loadings rates and sample preparations on the withdrawal performance of self-tapping screws.
