The sheet on the next page shows a proposed Fastfood building structure. Fig. 1 shows the plan view, and Fig. 2 shows a section through the structure. The roof is comprised of a reinforced concrete slab. This roof slab is supported by three masonry walls on grid lines A, B, and C as shown. The Architect desires that the walls on grid lines A and C be of 100mm thick unreinforced and ungrouted masonry concrete hollow vertical-cell units. However, the wall on grid line B must be reinforced masonry of clay hollow vertical-cell units, but can be of any thickness and degree of grouting. The following are the loading conditions:- Roof Unfactored Dead load = 4.2 kN/m2 Roof Unfactored Live Load = 2.0 kN/m2 Wall Unfactored Lateral Hurricane Wind Load (on each wall) = 1.8 kN/m2 Do the following:- (a) Check the adequacy of the proposed 100mm thick unreinforced masonry walls on grid lines A and C. [50 percent] (b) Design the reinforced masonry wall on grid line B. [50 percent] [To answer these questions, you may make any assumptions deemed necessary.]
