QUESTION 1 FLAT SLAB [44 MARKS] The figure below represents an 8m x 6.5m panel, 200mm thick flat slab with 2500mm square x 450mm drop (overall drop thickness is 450mm). The slab is supported by 350mm square columns as indicated. There are four panels in the direction of the long span and seven panels in the direction of the short span. Stability is provided to the structure in both directions. The slab supports a live load of 3kN/m², 0.25kN/m² finishes including the screed. The slab is to be constructed using grade 25/19 concrete and high tensile reinforcement with a minimum cover of 40mm 8m 8m 2 500 20p 6.5m Ta 6.5m X 350 1.1. Determine the ultimate force (F) in both directions that the panel is subjected too. (9) The nominal dead load, Dn = 5.05 kN/m2 The Ulimate load, n = 10.86 V kN/m2 ha 6.25 X m (round off to three digits) Bending-long span Effective span (0) = 6.79 m (round off to three digits Total force F 479 V KN Bending - short span Effective span (1) = 5.29 X m (round off to three digits Total force F 459 X KN
