In structural engineering, beams and columns are both essential components of a building's framework, but they serve different purposes and undergo different types of loading.

Beam:

Beams are horizontal structural elements that primarily resist bending loads.

They typically span between supports such as walls, columns, or other beams.

Beams are designed to carry vertical loads (such as the weight of the floors or roof) and distribute these loads to the supports.

They are characterized by their length, depth, and cross-sectional shape, which are optimized to resist bending moments and shear forces.

Column:

Columns are vertical structural elements that primarily resist compressive loads.

They transfer the loads from the structure above (such as beams, floors, and roof) to the foundation below.

Columns are designed to withstand axial loads, which are forces applied along their longitudinal axis.

They are typically characterized by their height, cross-sectional shape, and the material used, all of which are chosen to provide sufficient strength and stability against buckling under compression.

Objective Type Question: Which of the following statements is true regarding beams and columns?

A) Beams primarily resist compressive loads, while columns primarily resist bending loads. B) Beams are horizontal elements designed to carry axial loads, while columns are vertical elements designed to resist shear forces. C) Beams transfer loads from the structure above to the foundation, while columns transfer loads horizontally between supports. D) Beams are characterized by their height and cross-sectional shape, while columns are characterized by their length and depth.
