Bolted connections on circular end plates

Abstract

Bolted connections on circular end plates are used on columns with circular pipe cross-section joints, duct joints, and another member's joint. SR EN 1993-1-8:2006 and technical specialized literature do not contain regimentations in the case of circular end plates. This code develops in detail the rectangular end plate calculus, which presents conceptual deficiencies, with negative effects on structural security (end plate plastification scenarios, plastic distribution of the bolt tensile forces). This paper presents the circular end plate constitution and calculus, as required in steel structural designing; the relations are based on the end plate elastic behavior and on the elastic distribution of the bolt tensile forces.
