Structural steel and lightweight steel are quite different in terms of steel fabrication, application, and fastening methods. Structural steel requires thicker and heavier fastening techniques such as welding, bolting, and riveting, where as light gauge steel can be easily fastened using steel screws, for example.
Light gauge steel is a term used to describe cold-formed or cold-rolled steel. This type of cold-formed metal improves construction methods and produces a more durable product. Unlike wood, light gauge steel does not rot and is lighter than structural steel or concrete.
Steelwork in construction includes beams, columns, joists, steel studs, and aluminum framing, all of which are crucial to the framing of buildings, bridges, and other structures.
About the Book
The purpose of this book is to present basic steel design in accordance with the new limit state code BS 5950. The book is primarily intended for under graduate students who are just beginning to learn about steel design according to the new standard, but it is also useful for recent graduates and designers who wish to update their knowledge.
The book covers the design of steelwork members and joints using the simple design method, and the scheme is the same as that used in the lead author’s previous book, Structural Steelwork Calculations and Detailing (Butter worths, 1973). In this book, the design theory behind the standard is presented, and individual elements and complete architectural frames are designed to illustrate the use of the standard.
The application of microcomputers in the design process is discussed and several programs are listed. Computer Aided Drafting (CAD) is also mentioned and recommendations for detailed design are provided.
A steel- framed building consists of a frame work that supports all the loads to which the building is subjected. Cross sections of three common types of buildings are shown in Figure 1.1.
