Abstract
A high and reliably reproducible preload level of bolts is essential for the fatigue behaviour of ring flange connections in wind energy. For the yield-point controlled tightening method as a potential alternative, the missing normative foundations for large bolt diameters must be created in steel construction. In accordance with this objective, the authors identify the stress state in the bolt during installation through measurements. In addition, plastic deformations of the HV-bolts are quantified by 3D scans. Further experimental investigations evaluate the structural integrity of the connection and the effect of high preloads in terms of the load bearing behaviour. First results indicate no reduction of resistance within the connection and HV-bolts have a sufficient deformation capacity against high preloads. Based on that experimental scope of a joint national research project, this contribution discusses the applicability of yield-point controlled tightening for HV-bolts.
