HSS – Fastener Options

There are basically 3 means of connecting steel hollow sections, which include: Welding Through-Bolting, and Blind-Bolting Welding is usually restricted to workshop joints and applied mainly in the fabrication of trusses, lattice girders and sub-assemblies. For more information on this go to Welded Joints Site welding should be avoided – it’s costly, often difficult and …

HSS – Beam to Column / Bolted Moment Connections

A moment connection is designed to resist rotation at the joint – most hollow section connections, unlike open section connections, will not allow a great deal of flexibility and will rely on the rotation capacity of the connection components of the incoming beam. These connections are defined specifically as Moment Resisting which means the load …

HSS – Beam to Column / Bolted Fin-Plates

Typical Examples Beam to column connections using Fin-Plates are probably the most widely used connection due to their relative ease of fabrication and erection. The main advantage lies with the fact that they are all Through-Bolted. The following examples show typical connections graduating for the simplest and most straightforward to the more complex (and costly) …

HSS – Beam to Column / Bolted End-Plates / Cleats

These connections are not generally regarded as Moment Resisting, but due to their configuration they will offer some resistance against rotation. The determining factor lies with the Rotation Capacity of the joint components. (For more about the rotation capacity go to Moment Connections) Typical Examples The first 4 examples show typical beam to column connections …

Steel Hollow Sections

Square, Rectangular, and Round Hollow Structural Section (HSS) The hollow section profile possesses a greater strength-to-weight ratio than conventional open sections which allows for a greater flexibility in use due to its enhanced efficiency and inherent resistance to compression and torsion. This makes them ideal for use as structural column, shafts, trusses, composite beams and …
