Learn : Limit state concept,Limit State of Collapse,Limit State of Serviceability Limit state is the acceptable limit of safety,serviceability requ.before failure. Limit state concept The aim of this method is that the structure should be able to withstand safely all the load that are liable to act on it throughout its life and it should also satisfy the serviceability requirements of limiting deflection and cracking. Limit state is defined as the acceptable limit of safety and serviceability requirements before failure. The most important limit states which are considered in design as are follows: (i)        Limit state of collapse. (ii)       Limit state of serviceability  Limit State of Collapse This limit state is also called as strength limit state as it corresponds to the maximum load carrying capacity i.e., the safety requirements of the structure. The limit state of collapse is assessed from collapse of the whole or part of the structure.…
