What is the difference between rigid and flexible foundation?
Flexible footing gets deflected/rotated according to the reaction it gets from the ground surface in contact. But in case of rigid footing it cannot adjust itself according the reaction from the supporting ground. Due to this reason those have different pressure pattern.
What is difference between flexible footing and rigid footing?
For the rigid footing, a single point load was applied on the footing, while for the flexible footing, a point load was prescribed on four rigid footings, which could move independently. The flexible footing was designed to ease the tracking of the footing movement, although the …
Why do rigid structures need some flexibility?
This allows the construction of objects which are flexible, since they change shape, but also rigid, since they hold their shape at each position. Force is needed to change the shape, but each configuration is stable, requiring no force to maintain it.
What is raft foundation when it is preferred?
a) Raft foundations are preferred in areas with poor soil bearing capacity, uneven settlement, and the presence of mixed soil types. These foundations achieves the load-bearing capacity through the distribution of stresses to a larger area.
Which foundation is best for building?

- Slab Foundation. Slab foundation.
- Wall Footing Foundation. Wall Footing Foundation.
- Crawl space Foundation. Crawl space Foundation.

What is the difference between rigid and flexible structure?
A rigid structure is just that and during an earthquake if a building cannot move with the earthquake seismic waves it gets shaken apart. A flexible structure is meant to be able to sway with the tremors is more likely to survive an earthquake that would destroy a rigid structure.
