TYPES OF FOUNDATION Lesson DRAFTING STRUCTURAL 4 LAYOUT AND DETAILS (SL) Foundation ❑the part of the building below the surface of the ground which is sometimes called the substructure. Foundation Members 1. FOOTING – portion of foundation of a structure which directly distributes the weight of the building over large area. Foundation Members 2. FOUNDATION WALLS – support the load of the building above the ground and transmit the weight of the house to the footing  Foundation Members 3. PIERS AND COLUMNS – Vertical members used to support the floor systems and can be used as sole support of the structure.  Piers - vertical loadbearing member Column - or pillar is a structural element such as an intermediate support for that transmits, through compression, the adjacent ends of two bridge spans. weight of the structure above to other structural elements below. Types of Foundation 1. Spread Foundation – includes all those type where the load is distributed to the soil by slender vertical members.  Types of Foundation 2. Pier Foundation - Concrete piers carry down the load to the soil of inadequate bearing power until a satisfactory foundation bed has been reached.  Types of Foundation 3. Slab Foundation - A solid slab is poured directly on the ground with footings placed where extra support is needed.  Types of Foundation 4. T - Foundation - Consists of footing where concrete wall or concrete block forming wall is placed forming an inverted T. This foundation is popular in structures with basement.  Types of Foundation 5. Mat Foundation - Assembles a mat in the foundation is spread over the entire area of the building floor.  Types of Foundation 5. Mat Foundation - Assembles a mat in the foundation is spread over the entire area of the building floor.  Kinds of Footings 1. Wall Footing – footing which supports a wall by extending along entire length of the wall.  Kinds of Footings 2. Isolated Footing– is one which supports a column, post, pier or other concentrated load.  Kinds of Footings 3. Combined Footing – Supports two column loads or three sometimes but not in a row.  Kinds of Footings 4. Cantilever Footing – Supports two column loads and consists of two footings connected together by a beam often called strap.  Kinds of Footings 5. Continuous Footing – is one which supports a row of three or more columns.  Kinds of Footings 6. Raft or Mat Footing– is one which extends under the entire building area and supports all the wall and column loads from the building.  Kinds of Footings 7. Trapezoidal Footing Identify what kind of footing is illustrated in each image. CONTINUOUS CANTILEVER ISOLATED RAFT WALL OR MAT TRAPEZOIDAL COMBINED 1.
