Hello all.
I´m Julio Mendez a bachellor degree mechanical engineer, right now içm desiging a crude oil tanks, I´ve read many things in the api tanks.
SInce we are making a conceptual tanks design we have not need many tanks details.
But i have many doubst about the sheell roof junction designs.
1) I have very clear that tanks will need, in the top, wind girdes only if it is roofless. how is the name of thaht girder ¿ top end stiffner?
2) for calculating the participating area wich areas have to be acount? I mean Wc, Wh. should I take in consideration the area augmented by the curb angle by ( 5.1.5.9)??
3)In self supported roof this area calculated by appendix F (figure f-2)should be compared with 5.10.5 or 5.10.6 and F5.1
4) In fixed roof this participating area with wich area has to be compared?

Than you very much, Kind regards.
