How many types of footings used in industrial building foundation.

Question

Accepted Answer

There are mainly three types of footings used in industrial building foundation.

The three types of footings are isolated footing, combined footing, and raft footing.
Isolated footing is used for individual columns, combined footing is used for two or more columns, and raft footing is used for the entire building.
The choice of footing type depends on the soil condition, load-bearing capacity, and the size of the building.
For example, if the soil is weak, raft footing is preferred as it distributes the load over a larger area.
Similarly, if the columns are close to each other, combined footing is used to reduce the number of footings required.
