Metal buildings have been very popular since the beginning of the 20th century up to the present time. These contemporary metal buildings are composed of a lot of individual materials which have emerged over time. The manufacturing efficiency of these metal buildings comes from the mass production of the materials wherein a manufacturer develops a uniform way of making these structures which is called a pre-designed system.
With the use of CAD (Computer Aided Design), the developers of metal buildings were able to provide their clients with more formats and variations in terms of the dimensions of the buildings. Because of this, the use of pre-designed structures is becoming less beneficial for people especially nowadays where all the metal building constructions are specified for a certain project only.
Metal buildings are mainly composed of five major components which are the combined force members, bending members, compression members, tension members and the connections. The tension members are the ones carrying the tensile forces or the pulling forces of a certain structure. The compression members are more popularly known as the posts, struts and the columns of a structure. The bending members on the other hand are the structure’s girts, lintels, purlins, spandrels, joists, girders and beams. The combined force members are more popularly known as the beam columns which are subject to axial and bending compressions. Finally, the connections of metal buildings are the ones responsible for putting the entire structure together. These connectors function as a bonding material which holds the building together, making sure that the parts are firmly put together.
