Introduction
Beams are structural elements that would withstand load by resisting bending. The bending force
from beam own weight and external loadings would be exerted into the beam, the external loads’
reactions would result to bending moment.
Structural features
Moment of inertia
Moment of inertia at a given axis would describe the difficulty an object would face while
changing its angular motion. It includes both the object mass and its distance from the axis
(Bischoff and Gross, 2010).
Beams stresses
The beams would experience tensile, compressive and shear stresses that would be
exerted by the applied loads (Belletti and Gasperi, 2010).
Types of beams
Beams are classified as;
1. Fixed beams – beams restrained from rotating though they have been beam supported on
both ends
2. Simply supported beams – beams that are allowed freely to rotate and are supported on
its end and no resistance moment would be experience
3. Overhanging beam – beams that extends beyond one of its end support
4. Continuous beam – extension of beams over two supports
5. Cantilever beams – beams projected and are fixed on one end
6. Trusses beam – beams that are strengthened by addition of cable from a truss

Types of failures
The types of failures include; material failure that would cause formation of plastic hinge, lateral
torsion that occurs along the beams’ length and buckling of beams on its cross-section. Plastic
hinge would be formed when the beam bending stress would have reach the beams; yielding
strength.
