Dear Kowheng

I've tried your excelsheet however i just want to clarify several things
1. In your weight calculation i see 3% increase is it based on code or just practice habit?
2. cmiiw, you assumed symmetrical tendon position in your calculation and one live end?

Tnx

[kowheng]

essenza,

1. % increase was prepared for deck slab formwork loads + designer judgement.
2. Symetrical tendon profile was used, you can use both/one end stressing.
