As of SAP2000 V14.0.0, shell reinforcement design is based on Eurocodes. The content of this article will be updated accordingly. |
The SAP2000 formulation for shell reinforcement design is based on the following publications:
...
- Marti, P. (1990). Design of Concrete Slabs for Transverse Shear , ACI Structural Journal, 87(2), 180-190.
The formulation is documented in the technical note Concrete Shell Reinforcement Design, available through Help > Documentation > Technical Notes > Concrete Shell Reinforcement Design.
...
Default shell design parameters, such as rebar cover, may be modified through Define > Section Properties > Area Sections, as shown in Figure 1:
...

Reviewing results
After analysis is run, design parameters may be reviewed through Display > Show Forces/Stresses > Shells by selecting the component type Concrete Design, as shown in Figure 2:
Figure 2 - Review design parameters
ASt1 represents reinforcement in the 1 direction of the shell, and ASt2 is in the 2 direction. The reinforcement calculated for either the top or bottom face of the shell object may be displayed separately, as shown in Figure 3:
