Load Distribution

Load distribution greatly affects the deflection. A load distributed equally along the length of a beam (line load) will cause less deflection than the same load being applied to the centre of the beam.

Little deflection with a line load.

Increased deflection with Point Load.

The depth of the profile of metal cladding is another important criterion in the design and use of metal roof and wall cladding. Given the same cross section area, the deflection of the profile will vary with the square of the depth, with the trade-off of higher buckling modes.
