E – 1218 – Spread Footings And Mat Foundations
Intended Audience: civil engineers, structural engineers, geotechnical engineers, geologists and other design and construction professionals
PDH UNITS: 3
What should you do when the required footings of a structure cover more than half the area beneath it? How can you design a raft or mat foundation to enlarge and combine the footings in order to cover the entire area?
This course developed by expert J. Paul Guyer, P.E. provides an introduction to the design of spread footings and mat foundations for buildings, towers, and other structures.
Raft or mat foundations 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 bridge over small, soft spots in the soil if the mat is adequately reinforced.
In particular, this online engineering course will give engineers and other design and construction professionals an introduction to tools that can be used to design spread footings and mat foundations on cohesive and cohesionless soils.
