SIMPLY SUPPORTED STRUCTURAL BEAM WITH TWO CONCENTRATED LOADS
Following calculator has been developed to find forces, moments, stresses, deflections and slopes in structural beam for a specific case which is two point loads on a simply supported structural beam.
Note: For more information on
shear, moment, slope and deflection calculations for different end constraints, please refer to "Beams; Flexure of Straight Bars" chapter of Roark's Formulas for Stress and Strain.
Definitions:
Distributed load: A load which acts evenly over a structural member or over a surface that supports the load.
Fixed support: Fixed supports can resist vertical and horizontal forces as well as a moment. Since they restrain both rotation and translation, they are also known as rigid supports.
Pin support: A pinned support resist both vertical and horizontal forces but not a moment. They will allow the structural member to rotate, but not to translate in any direction.
A pinned connection could allow rotation in only one direction; providing resistance to rotation in any other direction.
Roller support: Roller supports are free to rotate and translate along the surface upon which the roller rests.
The resulting reaction force is always a single force that is perpendicular to the surface. Roller supports are commonly located at one end of long bridges to allow the expansion and contraction of the structure due to temperature changes.
Simply supported beam: A beam which is free to rotate at its supports, and also to expand longitudinally at one end.
Structural beam: A structural element that withstands loads and moments. General shapes are rectangular sections, I beams, wide flange beams and C channels.
