I Beam Roof Structure

The figures are based on quality materials.

I beam roof structure.

The bottom half is carried by the exterior bearing walls. The multi span beam calculator is a great tool to quickly validate forces in beams with multiple spans and load. Erection of steel beams. Use it to help you design steel wood and concrete beams under various loading conditions.

The i beam also called the h beam wide beam w beam universal beam ub and rolled steel joist is the shape of choice for structural steel builds. The image below shows a cross section of our simple 12 x 13 house from the joist span tables section of this tutorial.
