Asbestos was a popular material for fireproofing steel structures up until the early 1970s, before the health risks of asbestos fibres were fully understood. The beams may be cased in concrete, plasterboard or sprayed with a coating to insulate it from the heat of the fire or it can be protected by a fire-resistant ceiling construction. In the case of the columns this is usually done by encasing it in some form of fire resistant structure such as masonry, concrete or plasterboard. The frame needs to be protected from fire because steel softens at high temperature and this can cause the building to partially collapse. Often in office buildings, the final floor surface is provided by some form of raised flooring system with the void between the walking surface and the structural floor being used for cables and air handling ducts. Another popular alternative is a floor of precast concrete flooring units with some form of concrete topping. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated mold, below a thick layer of concrete and steel reinforcing bars. The central "web" of the steel I-beams is often wider than a column web to resist the higher bending moments that occur in beams. Steel beams are connected to the columns with bolts and threaded fasteners, and historically connected by rivets. Square and round tubular sections of steel can also be used, often filled with concrete. The two wide flanges of a column are thicker and wider than the flanges on a beam, to better withstand compressive stress in the structure. Simplify and optimize the design and construction of a short wall or half wall in residential and commercial cold formed steel framing.The rolled steel "profile" or cross section of steel columns takes the shape of the letter " I". Select from a variety of common trusses, or create your own truss to design the members, connections, fasteners, and lateral bracing elements.
