Content: For example, consider a bridge that can resist service loads without collapse. This is a "stable" structure. Now assume that this bridge shows abnormal deflections. The deflections could be such that the bridge feels bouncy and could lead to steering problems for vehicles crossing it at high speeds. As such this may not cause the structure to collapse. So we can say that the structure is stable, but according to serviceability criterion it is not serviceable because people could feel afraid of using the bridge. In the design and construction of the foundation and framing for buildings and bridges, the main materials used are concrete, steel, timber, and masonry. Steel can further be subdivided into two subsections: hot-rolled steel and cold-formed steel. Cold-formed steel applies to material of approximately 1/8" or less in thickness that is either folded or roll-
