If the rigidity index of soil is less than the critical rigidity index, then the soil compressibility factors are
- A0, 0, 0
- B1, 1, 1
- C< 1, < 1, < 1Correct
- D> 1, > 1, > 1
Solution
Concept
Vesic compressibility factors
Step-by-step solution
1. If Ir < Ir,crit, the compressibility factors are less than 1.
Explanation
Local or punching shear reduces capacity.
Why the other options are wrong
Factors of 1 mean no reduction.
Shortcut
Ir < Ircr → factor < 1.
Correct answer: C) < 1, < 1, < 1
