The limit state method is advantageous because all the limit states are checked to ensure that they will survive future conditions such as structural stress. The limit state method ensures that the structures can withstand a lot of pressure and remain durable.
Yes we can use limit state design for water tank design....
Working stress method of design based on the elastic theory in which materials, concrete and steel are assumed to be stressed well below their elastic limit under the design loads. Working stressess (permissible stress) for the materials are determined by dividing the ultimate or yield stressess by suitable factor of safety values. Limit state method of design based on limit state concept, te structure shall be designed to withstand safely all loads liable to act on it throughout its life;It shall also satisfy the serviceability requirements, such as limitations on deflection and cracking. The acceptable limit for the safety and serviceability requirements before failure occurs is called a "limit state". The aim of design is to achieve acceptable probabilities that the structure will not become unfit for the use for which is intended, that is that it will not reach a limit state...
because by these method all loads are considered ,and the structure is designed to undergo these loads
Limit state design
The arbitary limit of water content that represents the boundary between the liquid & plastic state is called as liquid limit.
limit state method
The limit state method is advantageous because all the limit states are checked to ensure that they will survive future conditions such as structural stress. The limit state method ensures that the structures can withstand a lot of pressure and remain durable.
working stress: in this a structure is designed by considering the stresses in its working condition..Limit state: In this the structure is designed by considering the stresses at different limit states. there are two limit states. ultimate limit state (situation in which structure collapse) and servicability limit state (situation in which cracks etc appears.)

The methods depend based on the type of structures. for eg. for water Retaining structures the Working stress method gives good life and for other structures which is not exposed to water, mostly limit state design works.

because by these method all loads are considered ,and the structure is designed to undergo these loads
factor of safety
the state with the highest speed limit is Texas
