In staircase shown in figure (slab-type stair), 1) Compute the load on the flight slab Sl. 2) Compute the maximum bending moment. 2 Riser height = 150mm and tread width=300mm. The live load 4kN/m², the weight of the covering material is 0.75 kN/m² for the stairs and 1.8 kN/m² for landing. Floor height = 3.3 m 3) If the required reinforcement for S1 is 7018/m, sketch the section reinforcement details. B2 at floor level floor level 1.70 + Bl at floor level B3 at landing level SI (SI 3.0 6.40 (S3) 1.70 1.70 B2 Hot 1.70 0.60, 4.0 landing level 2 A flat-plate floor system with panels 6.0 x 7.0 m is supported on 500 mm square columns. Using the ACI Code equations, a) Determine the minimum slab thickness required for the interior and corner panels shown. b) Compute the statical moment, Mo in the slab interior panels in both directions. • Edge beams are not used.
