Abstract
Shear connections of bearing type are one of the most commonly used types of bolted connections. This type of connection effectively transfers the load, when there is no gap between the bolt and the connected elements, the elimination of slack is often associated with a slipping. Neglecting the slip in an non-preloaded connection is a design error, which in some cases might lead to structural damage. The study presents the ways of taking into account the slip in connection in the analysis of the structure. The authors discuss the analytical approach based on the Fontviolant formula and the numerical approach in which software supporting the design of building structures is used. The aim of the study is to determine the influence of slip in non-preloaded bolts on the deflection of truss structures. The basis for the conducted analyses was the damage to a conveyor that was subject to major deformations as a result of excessive slip in incorrectly designed bolted connections. Theoretical analyses were carried out for flat trusses and they were expanded to cover the most commonly used types of trusses. The paper discusses the difficulties, pointing, among others, to random parameters that affect the capacity of the connection. The obtained results confirm that it is necessary to take into account the slip and its significant influence on the value of structural deflection. They also provide a set of results that can be used as initial reference for the slip calculation. Especially, the influence of slip in non-preloaded overlap bolted connections on the global deformations of the structure.
