Cold-formed steel has been widely used in building construction,from residential houses to industrial buildings. When a steel section is cold-formed from flat sheet or strip,the yield strength,and to a lesser extent the ultimate strength,is increased as a result of this cold working,particularly in the bends of the section.An Overview of Cold-Formed Steel Structurestemperatures while the cold-formed steel shapes are formed at room temperature.Cold-formed steel structural members are shapes commonly manufactured from steel plate,sheet or strip material.The manufacturing process involves forming the material by either press-braking or cold roll-forming to achieve the desired shape.Examples of the cold-formed steel are corrugated steel roof and floor
Light-Gauge Steel Sections (A design based on the working stress method) 12.1 Introduction.Light-gauge steel sections are also known as cold formed steel sections.These sections are made from thin sheets of uniform thickness without the application of heat.The thickness of the sheet used is generally between 1 mm and 8 mm.Author Zhen Nie,Yuanqi Li,Yehua WangPublish Year 2020Technical Guide for Cold-Formed Steel Framing Products1.Where AISI S100-16 is referenced,it is the North American Specifi cation for the Design of Cold-Formed Steel Structural Members,2016 Edition,with US provisions.2.The strength increase from cold work of forming has been incorporated for fl exural strength per Section A7.2 of AISI S100-16.3.
