Influence of Strain‐hardening on the Load‐carrying Behaviour of Bearing Type Bolted Connections

The investigations presented in this conference paper focus on the hole bearing resistance of symmetric single-bolt connections, taking into account distinct hardening behaviour various steel grades and quantifying its impact resulting load-carrying behaviour. They synthetize findings a larger study that was published full previous publications by authors. main put limitation deformations defining corresponding “resistance”, which is thus quantity with background an implicit deformation limitation. Experimental were carried out four different grades, each eight geometries, order to investigate influence deformations. presents new approach define point load-deformation curve between acceptable excessive Based results tests combination transition deformations, adapted model presented. In model, taken account, whereby here specifically ratio fu/fy tensile strength yield influences load-bearing proposed adaptation verification takes facilitates optimal use material can save resources. format remains almost unchanged, should simplify applicability practice.
