2.0 Figure (2) shows the floor plan of an office building with Live load intensity of 4 KN/m. No projected beams were allowed except on axes D, G, 1 & 4 as shown. Using Hollow block slab system, it is required to: a. Compute slab thickness, block size and arrangement of a one-way hollow block slab system enclosed between axes 1-4 and A-D. Draw the statical system of ribs along a vertical strip between axes 1-2 showing the appropraite arrangement of the steel re-bars (without calculations). Illustrate the concrete dimensions of the slab along a vertical section between axes 1-2 and horizontal section between axes B-C. b. Illustrate the block size and arrangement if a two-way hollow block slab system wwas used between axes 1-4 and A-D. Draw the statical system of ribs along a vertical strip between axes 23 showing the appropraite arrangement of the steel re-bars (without calculations). 2 (4) 0 7.0m 50 m 3.0 m 3.0 3.5 4.50 4.30 6 4.60 5.10 Figure 2: Floor plan of an office building 2.0 Figure (2) shows the floor plan of an office building with Live load intensity of 4 KN/m.
