Abstract:

Slippage corresponds to the relative displacement of a bolted joint subjected to shear loads sincethe construction clearance between the bolt shank and the bolthole at assembly can cause joint slip.Deflections of towers with joint slippage effects is up to 1.9 times greater than the displacements obtainedIn this study, 8 different types of joints are modelled and studied in the finite element program, andFinally, joint slip data for different types of angles, bolt diameter and bolt arrangements are generated
