The I beam overhead crane is a single girder overhead crane, with the I beam as the overhead crane main girder, supporting the lifting mechanism, the wire rope hoist or electric chain hoist. As in the hoist and crane industry, the I beams are also widely used in I beam hoist, I beam crane, I beam jib crane, I beam overhead crane, etc. I-beams may be used both as beams and as columns. Tables are available to allow easy selection of a suitable steel I-beam size for a given applied load. I-beams are widely used in the construction industry and are available in a variety of standard sizes. I-beams are commonly made of structural steel but may also be formed from aluminium or other materials. Plate girder, formed by welding (or occasionally bolting or riveting) plates.Rolled I-beam, formed by hot rolling, cold rolling or extrusion (depending on material).For a beam spanning a 12-foot room and supporting a weight of 600 lbs., the maximum bending moment would be 12 x 600/8 = 900 foot-pounds.An I-beam, also known as H-beam, W-beam, Universal Beam, Rolled Steel Joist, or double-T (is a beam with an I or H-shaped cross-section ). The bending moment is the length of the span times the weight to be supported divided by 8. How to calculate the bending moment of a beam?Ĭalculate the maximum bending moment for the wooden beams. Multiply the maximum bending moment of 900 foot pounds by 12 to get 10,800 inch-pounds. The latter is 1,150 pounds per square inch. How do you calculate the section modulus of a wooden beam?Ĭalculate the beam’s section modulus by dividing the maximum bending moment by the allowable fiber stress for wooden beams. Self-weight is equal to the RC unit weight (24 KN/m 3) times the beam’s volume. The beam’s dead load is equal to its self-weight and any other dead load from the slab and finishing works. Calculate the load on the reinforced concrete beam. How to calculate load carrying capacity of an existing concrete slab?įor two way slab, the tributary area can be used to transfer loads to the beams on all sides of the slab. For rooms which are heavily frequented, it may be 50 lbs. per square foot for northern areas of the U.S. For a flat roof with snow loading, this is 25 lbs. Calculate the weight the beam must support.

How to calculate the weight of a load bearing beam? In the early days of the industry, hvac companies made an educated guess to determine the heat gain and loss for the home. If you have a beam of steel which has a basic permissible bending stress of about 23000 lbs per square inch, by the time you make allowances for the span and the lack of restraint, the actual bending stress that the beam can handle is down to about 6100 lbs per square inch under these conditions.Ī load calculation is the process of determining the proper size of a furnace and/or air conditioner for a home.
