Hollow structural section Connections and trusses – a design guide

What are hollow structural sections used for?
HSS, are cold-formed, welded steel tubes used for welded or bolted construction of buildings, bridges, and other structures as well as a wide-range of manufactured products. They are produced in square, round, and rectangular shapes to meet structural design requirements.

Hollow structural sections typically come in three main forms: rectangular hollow sections (RHS), square hollow sections (SHS) and circular hollow sections (CHS). Each type of hollow section has its benefits, properties, and purposes.

There are three types of hollow structural sections rectangular hollow sections (RHS), square hollow sections (SHS), and Circular Hollow Sections (CHS). Each hollow section has its own set of advantages, properties, and applications.

There are two basic methods of producing hollow sections – the seamless process in which a hole is pierced through a hot solid bar to form the bore and then the bar is rolled to form the round tube, and the welded process in which a steel plate or strip is formed into a cylindrical shape and the edges welded together.

This book, a compendium of current design information on the topic of Hollow Structural Section connections and trusses, is directed to practicing structural engineers.

Connection strength frequently governs the selection of HSS members in structural steelwork, and the impracticality of proving internet reinforcement can pose concerns behaviour at the conceptual design stage, subsequent connection reinforcement can frequently be averted, and maximum economy gained from the use of HSS.
