Dear Tushar,

All these things appear too much theoretical to me. Some of the things we must keep in mind while analysing.

  1. What we are analysing should be implementable and executable at site.
  2. what we are analysing should be correct scientifically and practically.
  3. The restraints are considered with infinite (very high ) stiffness in the softwares that we use, unless we explicitely state the support stiffness.
  4. The linear static coefficient of friction between sliding surfaces is assumed as 0.3 Who knows, what it will be at site, in dynamic condition ?
  5. The solvers of the software do have a marginal error in calculations. I think due to this error though you provide exact gaps and all, you will get only one restraint active among three.

For academic interest, we can run such problems, but never in actual cases.
