E – 1218 Spread Footings And Mat Foundations
$75.00
Courses Included
This course provides an introduction to the design of spread footings and mat foundations for buildings and other structures such as towers. When required footings cover more than half the area beneath a structure, it is often desirable to enlarge and combine the footings to cover the entire area. This type of foundation is called a raft or mat foundation and may be cheaper than individual footings because of reduced forming costs and simpler excavation procedures. A mat foundation also may be used to resist hydrostatic pressures or to bridge over small, soft spots in the soil, provided the mat is adequately reinforced.
This course will give engineers and other design and construction professionals an introduction to tools that can be used to design footings and mat foundations on cohesive and cohesionless soils.
