General Options
Header | Description |
|---|---|
Effective Length Factor, k | effective length factor for piles/columns. |
EI Multiplier | Member stiffness multiplier. |
Slenderness Method | Chooses which method will be used to calculate slenderness in the member. ACI uses LRFD 9th Ed. 5.6.4.3, where Secant uses the secant method as described in the ACI Journal, Arthur R. Anderson and Saad E. MOUSTAFA, “Ultimate Strength of Prestressed Concrete Piles and Columns” |
Part of Seismic Resisting System | Is the pile part of the seismic resisting system. Spiral provisions vary depending on whether the pile is part of the structure’s seismic-force-resisting system. |
Resistance Factors
Header | Description |
|---|---|
Shear, ϕshear | The resistance factor for shear. |
Flexure, ϕFlex | The resistance factor for flexure. |
Compression, ϕComp | The resistance factor for compression. |
Service Stresses
These are multipliers that return service stress limits.
| Note |
