There is no limit.
People can reduce damage from tornadoes somewhat by reinforcing the connections between roofs and walls and between walls and foundations. Building houses with hip roofs rather than gabled roofs also helps.
A design concept is an idea for a design. For instance a design concept for a website might sounds like "It will be mostly dark muted colors with some orange highlights, and use the theme of circles that will be repeated throughout the site". It is usually accompanied with a design mockup, which is a representation of the idea that isn't fully finished or implemented the way the final product will be. For instance a mockup for a web design might be a screenshot instead of a rendered webpage. A mockup for a business card might be a few verisions of the design idea printed out on a sheet of paper instead of the final run of printed cards.it is a general idea for the drawing. it help to know and identify all the process under taken in the design process.

Yes we can use limit state design for water tank design....
limit state method
in reinforced concrete design
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.)
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...
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.
factor of safety
because by these method all loads are considered ,and the structure is designed to undergo these loads

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.
It is a constraint
i think , because water tanks are more vulnerable structures and plus the tank is sometime overfilled and sometime empty, the pressure inside is so varying, its needs more safety precautions and as we all know working stress method assumes more safety factor than limit state design, which is an economical design, we prefer to use working stress method...
