WebWhen the tributary area is used, the position of floor beams is not taken into consideration, but an allowance for their weight is included. Designers can use the tributary area to calculate live loads, given that the design codes specify the percentage of live loads transmitted to a column is an inverse function of the tributary areas; that is, as the … WebFor two way slab, the tributary area can be used to transfer loads to the beams on all sides of the slab. Calculate the load on the reinforced concrete beam. The beam's dead load is equal to its self-weight and any other dead load from the slab and finishing works. Self-weight is equal to the RC unit weight (24 KN/m 3) times the beam's volume. WebS 40 psf Second and Third Floor Loads width of 6 ft determine the factored moment Dead load, 40 psf 25.
