Moment-rotation characteristics for deconstructable flush end plate composite joints

Abstract

A 3-D finite element modelling of flush end plate semi-rigid beam-to-column composite joints is described. The joints comprise of deconstructable post-installed friction-grip bolted shear connectors. The moment-rotation characteristics for these prototype joints subjected to a hogging bending moment with the influence of partial shear connection is investigated using ABAQUS, including material and geometric non-linearities. The accuracy and reliability of the numerical formulation are verified against experimental data, and a parametric study is conducted. Momentrotation models for deconstructable flush end plate beam-to-column composite joints are proposed from these results. © 2020, American Institute of Steel Construction, AISC. All rights reserved.
