Advanced procedures for design of bolted connections

Abstract

Design of bolted slip resistant connection are integral part of design of steel bridges. In recent years, Component Based Finite Element Method (CBFEM) has been increasingly expanding in modelling of structural joints. The proper models of bolts play the major role in prediction of connection stiffness, resistance and deformation capacity. This contribution will describe the influence of pull and shear interaction for correct design of a group of bolts. The second part will be focussed to an advanced model of slip resistance bolts. The last chapter presents the advantages of procedure on examples of various bridge connection, which design was supported by CBFEM.
