An option is provided to save diaphragm shell forces during analysis. This information is used to calculate diaphragm cross-section forces at a user-defined location after analysis. If this option is not selected, no diaphragm cross-section force is reported.

Also included is an option to store diaphragm stresses and internal forces for analyzed load cases. If the option is selected, diaphragm stresses and internal forces are stored. This information is later used to display diaphragm stresses and internal forces on screen.
