Dear Bentley,

I request to update SACS ring utility programme based on latest Roark's Formulas for Stress and Strain book.

Further, the following update is desired.

The unit system of present Roarks program should be updated for MKS/SI system

The input is not able to be saved. Hence, user should be able to save input, like Basic static analysis is saved in data gen.

All load cases (as available in Roarks book) should be included as much as possible.

Von mise stress , direct stress, shear stress, bending stress and combine stress should be reported and AISC Y& API codes to be included

Results should be available at every 5 deg.

Bending moment diagram and stress diagram should be able to be printed.

Thanks
