yes, Checks are always ALWAYS done for the serviceability limit state (SLS) of loading which includes dead load and live load.
Cables are given different profiles exactly for the purpose of countering tensile stresses from the best to worst possible positioning of live loads.
There are different levels of prestressing.
- Full prestress: There is no tension in the concrete section at SLS..
- Limited prestress: Concrete may develop tension but it should definitely be within tensile strength (i.e. no cracking at SLS)
- Partial prestress: Concrete may crack due to tensile stress at SLS and crack width checks have to be performed.
All the above usually caters only to the location of cables !
Most pretensioned structures fall under the fully prestressed category because we definitely don't want cracking which exposes the strands to corrosion.
In contrast, post tensioned structures are majorly partially prestressed (cables are anyway safe within ducts so why not allow concrete to crack a bit ?)
can be possible only to a permissible loads and its of higher for live loads but it cant be possible to give a Prestressed concrete bodies to completely nullify.
