Building Systems and Components
A building system was defined earlier as all work components necessary for a particular type of building together with their execution procedures and techniques. Building systems can be classified in different ways, depending on the particular interest of their users or producers. A frequent basis for such classification is the construction technology. In this manner four major groups can be distinguished: systems with (1) timber, (2) steel, (3) cast in situ concrete, and (4) precast concrete as their main structural and space-enclosing material. Various composite solutions are also prevalent, for example, steel framing with concrete or timber floor slabs, cast in situ concrete beams and columns with precast concrete slabs, and precast concrete framing with brick masonry.
