Structural components of framed construction

It is a rigid and stable framework of structures that consists of structural members like slabs, beams, and columns that can resist the deformation due to the self-weight and high external loads and transfer the applied loads safely to the substructure and consecutively to the ground. It is made of different materials, such as reinforced concrete, steel, and wood. In ancient days, load-bearing structures were used to build houses and houses were built using load-bearing walls.
