Numerical Tests of Steel Beam-to-Column Semi-Rigid Connections

Abstract

This paper presents an analysis of semi-rigid beam-to-column connections in which the beam is connected to column not at 90 degrees angle. Beam-to-column bolted end-plate connections that are subjected to pure bending were modelled by three-dimensional finite elements. Numerical modelling of connection covers the geometrical and material non-linearities as well as contact and separation between various components of connection. Moment-rotation M-<I> curves for modelled connections using numerical results are made and stress distribution in connection components is presented. The study shows a significant influence of inclination of beam and quantity and location of bolts on the joint rigidity.

Behaviour of semi-rigid steel beam-to-beam joints under bending and axial forces

“…Testing of finite element mesh density for accuracy of the results was performed for the analysed joint. Most influential to the accuracy of results was the finite element mesh density of end plates [18].…”

Component method extension to steel beam‐to‐beam and beam‐to‐column knee joints under bending and axial forces

“…Also, calculations of these joints were performed by finite element method when the joints are loaded by bending moments [15].…”
