In this method of design, the is designed to withstand the safety of for all loads liable to act on it throughout its life, it also satisfied the serviceability requirements such as limitation on deflection and cracking. The aim of design through this method is to achieve acceptable probabilities that structure will become unfit for use to which it is built. It means that it will not reach a limit state or critical state. All relevant limit states should be considered in design to ensure an adequate degree of safety…
