Loft Beam Calculator

This calculator matches up with 90 of the applications in the 2012 international residential code book.

Loft beam calculator.

Length of beam is the total including all spans of the beam in mm or ft. In addition to this requirement the new steel beams afford the modified roof support via eaves partitions. Young s modulus is set to a default value of 200 000 mpa or 29000 ksi for structural steel but can be edited by the user. It can also be used as a beam load capacity calculator by using it as a bending stress or shear stress calculator.

If there is are any questions about anything else then you should contact your supplier or an engineer. Most interior beams need to include the roof load. In all but a very few cases steel beams are required to carry the new floor where load bearing walls are not available. Area of the cross section is specific to the beam section selected and is defaulted to the values.

The properties of the beam and section are specified by typing directly into the input fields. These nine beam spans are for built up beams made up of either 2x8 2x10 or 2x12 dimensional lumber nailed together as either 3 4 or 5 ply beams. There are companies which carry out structural calculations as well as providing drawings they may produce 3d visuals as well. For example a 3 ply 2x8 beam would use three 2x8s nailed together side by side.

The above steel beam span calculator is a versatile structural engineering tool used to calculate the bending moment in an aluminium wood or steel beam. It has been my experience to never use a beam smaller than a two ply 2 x 8. For help in understanding the results in the calculator read the section above on how to read beam span tables. Other structural calculations will consider the beams joists posts and rafters all designed to produce a loft conversion that is safe and meets all necessary building regulations.
