Limit state method (Topic: 12003)

Using the limit state method the structure is proportioned on the basis of its maximum strength (resistance). This strength, as determined by rational analysis, shall not be less than that required to support a factored load equal to the sum of the factored live load and dead load. (Ultimate limit state). Or the structure is proportioned on the basis of its maximum allowable deflection. This deflection is determined by the use of the structure (serviceability limit state).

Limit state method

Requirement: Design resistance > design load
