For the Flat Slab or One-way slab and joist (approximate 2'-6" spacing) concrete system, layout the system for a 120ft (36m) x 150ft (45m) building. DO NOT USE THE SAME SYSTEM THAT YOU STUDIED. Cleary show and label the columns and dimension the bays. Make sure you are using the correct bay proportions. Sketch at least one bay in detail. Sketch a section through the system, either overall or a detail, whichever is appropriate. State the effective span range of the system. State the typical depth to span ratio that is used to find the preliminary height h of the system. Using your layout and plan show how you would determine the height h for the elements within the system given a certain bay size. Label your framing plan or section with the depths of the structural elements. Clearly show which direction(s) the elements are spanning.
