In structural engineering we give names to different structural members based on their behaviour under applied load. Beam and column is also two structural members.
Check out this post to know more about columns and its types and for beams check this one.
For example:
Say you have a rod of length 3 m made out of steel and a load P to support.
- You decide to hang the rod from ceiling and hook the load to the other end of the rod. The transfer of load in this case is primarily by tension and thus we call it a Tie.
- In the second case, keep the rod vertically on the floor and place the load is on top of it. Now the transfer of load is by compression and thus we call it a Column.
- In the third case we keep the rod on two supports and then place load on top of it. This time the primary mode of load transfer is by bending and thus we call it a Beam.
- In the fourth case we keep the rod vertical and apply load horizontally to it. This time the primary mode of load transfer is also by bending and thus we call it a Beam.
- In the fifth case we keep the rod vertical and apply the load at a distance from its centroidal axis. This time the load in addition to compression also produces bending moment in the member and thus we call it a Beam-Column (Bending and Compression).
It is important to notice here that in all the above five cases nothing physically got changed with the rod in term of its material properties, cross-section or length. The only thing that changed was the way in which the load was being transferred by it.
You can use our android application to design all the different reinforced column sections.
