We might get this confusion. When there are so many geometric shapes, why are we still widely using only two types of columns more often? (square, rectangular)
Also, when we see the circular column? We may start to think. Does the circular column really give strength and durability to the structure?
Let’s discuss this…
All three geometric shape columns, such as rectangular, square, and circular, have no difference in a structural capacity. It will be designed in such a way that it would carry the loads perfectly. Moreover, it all depends on the designer.
Let’s forget about the columns; just focus on the geometry parts alone to better understand this.
The circular or cylindrical shape is symmetry. Whereas a square has 4 axes of symmetry, and a rectangle has 2 axes of symmetry. So circular columns will have the same moment of inertia at all axes to avoid buckling failure.
What is Symmetry? The geometric shape is symmetry if it can be divided into two identical pieces that are arranged in an organized fashion. If you see the above picture, after drawing 4 axes, the square becomes symmetrical. All individual parts are identical.
Load Handling Differences
Which one is better? All three columns are the best. The choice is decided by the location of the column or by the designer or architect.
