I Beam Floor Slab

Types of loads on columns.

I beam floor slab.

The picture below shows what the framing for this floor would look like in a three dimensional perspective. Steel beam members can span up to 18m but the most usual range of steel beam spans rang from 3m to 9m. The weight of the concrete slab would then cause the cambered beam to deflect to a level plane at the speci fied eleva t i o n. F is the bending stress.

The traditional reinforced concrete beam and slab floor has an economical span l of d x 15 for a single span and d x 20 for a multi span where d is the depth of the slab plus beam. Get the beam depth say d of the selected steel i beam. Concrete floor systems are reinforced slab structures designed to satisfy a range of loading and span conditions in a building designed to span in either one direction one way or both directions two way of a structural bay the range of concrete floor systems available are created to economically and efficiently account for the numerous and specific demands of each building project. In conventional slab beam system the load is transferred from slab to beam and ultimately beam to the column.

The load is transferred directly from slab to column in the flat slab. Concrete floor systems are designed to span in either one direction one way or both directions two way of a structural bay. Concrete floor systems are reinforced slab structures designed to satisfy a range of loading and span conditions in a building. The floor joists are still 12 long but now you can see a floor beam running horizontally across the middle of the house supported by the lower concrete foundation wall.

Find out the area moment of inertia say i of the selected steel i beam. A concrete slab of uniform thick ness can be placed by positioning the screeds at the high and low points of the cambered beam. Columns transfer vertical loads from a ceiling floor or roof slab or from a beam to a floor or foundation. Contact your supplier for product availability.

Referenced dimensions are nominal and used for design purposes. Now use the following formulae for calculating stress developed f in the beam. B e r ing the beams is the key to achieving a nearly level floor fi g u re 2. Various prefabricated beam sections are available to be used in the construction multi storey steel frame structure.

The depth of slab between the beams can be initially sized using the span to depth ratios for a flat plate. Wood i beam joist features and benefits all wood i beam joists have an enhanced osb web. Not all products are available at all supply centers. Beams commonly transfer loads from floors and roof to the columns.
