Design of Steel Structures: Materials, Connections, and Components systematically introduces the basic concepts and principles of the subject of "Design of steel structure". Sections cover materials, failure modes of steel structures, members under tension, compression, bending and combined loads, steel connections, typical steel structural systems, composite members and vibrations resistance of steel members and connections. In addition, development history and the general application of steel structures are introduced, along with development status trends and typical classifications of steel structures. Other chapters discuss materials of steel structures, including high-performance steel, cold-formed steel, and other new types.
