Numerical and theoretical investigation of bolted sleeve connections with rectangular hollow sections

This article presents a theoretical and numerical study of bolted sleeve connections with rectangular hollow sections (RHS) under axial tension compression. The geometric form section provides resistance for high loads, torsion combines effects, spreading its utilization in truss systems. In this context, the proposed explore these characteristics RHS offer an attractive aesthetic appearance continuity elements. connection is formed by two outer tubes connected inner tube staggered bolts. Herein, parametric was developed identification failure modes connection. Finite element models different parameters number bolts were created commercial software. width, depth thickness diameter variated. theoretical/numerical/parametric results, yielding gross failure, fracture through effective net area bearing observed. These occurred both tubes. load results compared to determine capacity connections. formulations evaluated representation ultimate modes.
