The steel framework shown below is used to support the reinforced concrete slab (unit weight of concrete =23.6KN/m3) that is used for an office use (minimum live load = 2.4KPa). The slab is 150 mm thick. Use a=3m, b=5m. Neglect the self-weight of the beam and girder. Assume all beams and girders have simple supports. NSCP 2015 Load factors: 1.2DL & 1.6LL.

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.
