/n Shallow Foundations Alternative (PART 2) A* M5: Shallow Foundations Alternative (Spread Footings) Based on column loads (from Part 1 of homework) and your generalized geotechnical stratigraphy, design embedded (D-T) footings for the structure. Each column will rest on one reinforced concrete spread footing. Each footing must meet bearing capacity and settlement criteria. DELIVERABLE The design of the shallow footings will be presented as Report 5: Footings Design Report. Note: The design of the shallow footings will also be presented in the final report of this course. The report must contain: Number 1&2 DONE IN FILE 1. an introduction section, with general information on footings, footing construction methods, and examples. The introduction must contain citations. 2. A design table with characteristics for each footing: (a) location, (b) column supported, (c) column load, (d) width, (f) critical factor of safety, (g) settlement associated with the structural load (as provided in module 4), (h) differential settlement ratios (with adjacent footings), and (i) cost. Report all relevant material parameters (e.g., concrete modulus) below the table. Sum the areas for all the footings and report this area Aner below the table. Compare this area to the structure's entire footprint area Ag, as a ratio: Astr/Anet (clearly, the ratio must be < 1). 3. Three appendices: 1. Settlement calculations for (i) the footing with lowest critical factor of safety, and (ii) the footing with highest critical factor of safety. 2. Capacity calculations for (i) the footing with lowest critical factor of safety, and (ii) the footing with highest critical factor of safety. 3. To-scale design drawings (profile with soil parameters included) for (i) the footing with lowest critical factor of safety, and (ii) the footing with highest critical factor of safety.
