Limit State Method (LSM)

Limit states stand for the satisfactory limits for the safety and serviceability requirements of the structure prior to failure takes place. The design of structures by this method will make sure that they will not attain limit states and will not become unsuitable for the use for which they are projected. The structures will not just fail or collapse by breaching (exceeding) the limit states. So, failure assumes that clearly defined limit states of structural usefulness has been surpassed.

Limit state are categorized in the following types :-

  • Limit state of collapse
  • Limit state of serviceability.
