Behaviour and design of bolted endplate joints between composite walls and steel beams

Abstract

This paper presents a finite element model for predicting the monotonic behaviour of bolted endplate joints connecting steel concrete composite walls and steel beams. The demountable Hollo bolts are utilised to facilitate the quick installation and dismantling for replacement and reuse. In the developed model, material and geometric nonlinearities were included. The accuracy of the developed model was assessed by comparing the numerical results with previous experimental tests on hollow/composite column to steel beam joints that incorporated endplates and Hollo bolts. In particular, the Hollo bolts were modelled with the expanded sleeves involved, and different material properties of the Hol..
