the floor framing plan of a reinforced concrete building. All beams are 300 mm x 600 mm. The properties are as follows: slab thickness = 100 mm; super imposed dead load = 3 kPa; live load = 4.8 kPa; concrete unit weight = 24 kN/m3. The columns at E and H are deleted thus girder BEHK alone supports beam DEF at E and beam GHI at H. Calculate the uniformly distributed service dead load at beam DEF in kN/m Calculate the uniformly distributed service live load at beam DEF in kN/m.
