Welcome to the course on the Theory of Columns. We all know that there are various element exists in the structure. These elements are column, beam, slab, foundation, etc. Every structural element plays an important role in a structure. We can say that these are bones of structure which gives strength to the structure so that structure is capable of carrying loads on the structure. Every structural element has its own identity. Every structural element is a medium of transfer of load.
So what do you mean by column? It is a vertical structural element that is subjected to an axial compressive load. We know that frame of beams (i.e. horizontal structural element) is connected to various columns. We can say that column collects the structural load from beams and transfer it to the foundation below. Then what is strut? Strut is also subjected to compression in a direction parallel to its longitudinal direction as like column. A strut may be used in a vertical position or in an inclined position in roof trusses. It is shorter than the column. Note that all columns are struts but all struts are not columns.
The material of the column may be RCC (Reinforced Cement Concrete) or it may be steel in the form of round bar or hollow section or any rolled sections available.
Columns are frequently used to support beams or arches on which the upper parts of walls or slab rest.
