Experimental analysis of beam-to-column connection with partially encased concrete column with varying inertia axis
Abstract This study investigates the behaviour of beam-to-column connections of partially encased steel–concrete composite columns and steel beams connected using endplates and bolts. Four cruciform connections were tested in the experimental program, with varying column positions to study the flexural behaviour about the weak axis of inertia. The objective of the study was investigating the effect of uninterrupted fibre-reinforced concrete in a connection region on the ultimate capacity and stiffness of the connection. The experimental results demonstrated the effectiveness of uninterrupted fibre-reinforced concrete at the connection, regardless of the axis of inertia of the column; the obtained strengths, rotations, displacements, and deformations were analysed.
Highlights Novel deconstructable arrangement for beam-to-column connection with partially encased column; Influence of the weak-axis and concrete filling of the composite column on the load capacity; More efficient behaviour compared to the conventional system with interruption concrete at the connection.
