Rex J. Andrews Beam Calculator

Please enter in the values to be used in the calculation.
IMPORTANT: ANY UNITS CAN BE USED BUT THEY MUST REMAIN CONSISTENT THROUGHOUT ALL VALUES.

The inertia calculations are based on the parallel axis theoreom, no calculations are performed for buckling or any other forms of localised failure
