Floor construction of the office building in Figure 1 consists of 3 mm thick PVC floor tiles(16 kN/m²) laid over 19 mm cement screed (23 kN/m³), 12.5 mm lime-plaster ceiling finish (19 kN/m³) on soffit, and light partitions. Assume 1 hour fire resistance, moderate exposure, fcu = 30 MPa. Consider both E-W & N-S spans. Assume Ø 12 mm and cover = 30 mm (a) Estimate the floor slab thickness (hint: Use Rules-of-thumb, fire requirement & span/depth ratios) (9) (b) Calculate Characteristic dead (Gn) and live loads (Qn) (5) (c) Calculate ULS & SLS design loads (4) (d) Draw the BMD labelling maximum moments at key points along the multi-span slab (7) B 6m X 6 m 6 m E-W beam FLOOR PLAN 3.5m m 3.5m 3.5m 3.5m N-S beams N 3.6m 3.6m 3.6m 3.6m 3.6m 3.6m Roof 5th 4th 3rd 2nd Grd fir ELEVATION, SEC.
