Influence of geometrical imperfections and residual stresses on the reliability of high strength steel welded I-section columns using Monte Carlo simulation

This paper aims to assess the influence of geometrical imperfections and residual stresses on the reliability of the stability design rules for steel columns in Eurocode 3 considering a full probabilistic approach and further validate the new buckling curves in the scope of the ongoing revision of the Structural Eurocodes. A reliability...

Lateral-torsional buckling resistance of non-prismatic and prismatic mono-symmetric I-section steel beams based on stress utilization

The lateral-torsional resistance of prismatic double-symmetric I-section beams is accurately predicted using a mechanically consistent Ayrton-Perry approach, combined with a calibrated generalized imperfection. The corresponding design formulation was recently adopted in the revised version of Eurocode 3. However, for prismatic mono-symmetric...

A model for the initial stiffness of the face plate component

The component method for joint analysis relies on the formulation of stiffness and strength of individual parts to derive the global properties of the joint. One of these components is the web of an open I-section, or the face of a rectangular hollow section, hereby referred to as face plate. It is currently not codified despite its frequent...

Design of pin connections between steel members

The design of pin connections between steel members has been established for many years in design codes. However, recently, in the scope of the revision of Eurocode 3, Part 1–8 (EN 1993–1-8), questions were raised concerning the safety of the corresponding design verifications. This paper identifies two main aspects that require revision,...

Calculation Methods for Steel Joints: Comparative Study of European Design Regulations and Partial Finite Element Analyses

Traditionally, steel joints are calculated by the calculation rules described in the Eurocode 3: NEN-EN 1993-1-8. Effective lengths are important parameters to determine the different resistances of the components in the steel joint. Finite Element Analyses (FEA)...

Fatigue of steel lock gates

The Netherlands contains more than 400 hydraulic structures, of which 120 are locks. Inspections carried out since 2010 by Rijkswaterstaat revealed that a number of cracks per lock gate have been found. Based on experience and an evaluation of the photos made during the inspections it is assumed that the cracks occur due to fatigue. At this...
