PROBLEM STATEMENT
To design a H structural beam with the loading shown below.
TASK APPROACH
A loading diagram was drawn, shear force diagram and a bending moment
diagram was drawn. A large I beam was selected tentatively from a table of
standard beams. using the properties of the selected beam, the maximum
shear and tensile stress were calculated using the maximum shear force and
bending moments read from the shear force and bending moment diagram
respectively. Stresses at critical stress were then determined.
MDSolids software was used to verify these results. An I beam was selected
and subjected to loading as per the task. The software was used to generate
shear force and bending moment diagrams. A beam similar to the one
selected was designed and material set to S275. Stress limits were input and
the stresses at critical points analysed.
A similar beam of the shape selected was modeled on Solidworks 2018.

 Loading diagram
We introduce a point at 8 m between point C and D
 Reaction at A: RA
We consider reactions about point F
∑ MyF = 0 + (assuming positive sign convention).
0 = (RA × 8) + (40 × 3 × 6.5) + (60 × 2) + (-40 × 1.5)
