Flexural behaviour of pairs of laminated unequal channel beams with different interfacial connections in corner-supported modular steel buildings

Abstract

In this study, the combined bending action of pairs of laminated unequal channel beams with different interfacial connections were introduced into corner-supported modular steel buildings with the aim of enhancing the interactions between the adjacent beams and modules in modular buildings. These laminated beams consist of C sections acting together by bolts through their flanges. First, a series of experiments were conducted on three laminated beams, i.e. a channel beam with simple interfacial contact interactions (LB-C), a channel beam with four additional shear bolt connections (LB-C-4B) and a channel beam with eight shear bolt connections (LB-C-8B). Mechanical testing on an independent b..
