This presentation provides information about shallow foundations. It defines a foundation as the part of a building below ground that transfers the building's weight to the soil. Shallow foundations are placed immediately below the structure and include spread footings, combined footings, mat/raft foundations, and grillage footings. Spread footings support columns and walls, and come in types like wall, column, and inverted arch footings. Combined footings support two or three close columns. Mat foundations consist of a thick concrete slab covering the entire bottom area. The presentation discusses the advantages of shallow foundations like quick construction and lower cost, and disadvantages such as limitations with expansive soils.
