Design using ACI 318-11, ACI 318-08, ACI 318-05, ACI 318-02, or ACI 318-99 in STAAD.Pro supports the design of beams, columns, or slabs defined as follows.
Section types for concrete design
Beam Design – uses a 2D beam element if specified with the following properties:
- Rectangular
- Defined as a Prismatic section with YD (depth) and ZD (width)
- Defined in a User Table, type: prismatic
- Tee Section
- Defined as a Prismatic section with YD (overall depth), YB (depth of stem), ZD (width of flange), and ZB (width of stem)
- Trapezoidal
- Defined as Prismatic section with YD (depth), ZD (width at top), and ZB (width at bottom).
Column Design – uses a 2D beam element if specified with the following properties:
- Rectangular
- Defined as a Prismatic section with YD (depth) and ZD (width)
- Defined in a User Table, type: prismatic
- Circular
- Defined as Prismatic section with YD (circumference)
Floor Slab Design - uses a 2D plate element
- 3-noded plate with thickness of element is equal to the thickness of the slab
- 4-noded plate with thickness of element is equal to the thickness of the slab. All four nodes should be co-planar.
