General Options
HeaderOption | 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” |
Show Mild Slenderness | This options enables the slenderness method chosen to be overlaid on the Mild Interaction Diagram. |
Seismic Detailing
Options that allow for a more accurate report on seismic detailing. If these options are omitted the worst case is assumed and reported.
Note |
---|
This will not affect the pile analysis. These options are not required but will make the Spiral Summary more accurate. |
Option | Description | ||
---|---|---|---|
Depth of Pile in Soil | The length of the pile that is under the surface of the soil. This is used in ACI seismic detailing.
| ||
Distance to Zero Curvature | This is the distance of the pile to the first point of zero curvature. This is used in ACI seismic detailing.
| ||
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. This is used in PCI seismic detailing. |
Resistance Factors
HeaderOption | Description |
---|---|
Shear, ϕshear | The resistance factor for shear. |
Flexure, ϕFlex | The resistance factor for flexure. |
Compression, ϕComp | The resistance factor for compression. |
...
These are multipliers that return service stress limits.
Compression Multipliers
HeaderOption | Description | ||
---|---|---|---|
Sustained | Compression multiplier for sustained loads limit.
| ||
Service | Compression multiplier for stripping and erection limits.
| ||
Transfer | Compression multiplier for transfer stress limit.
| ||
Sustained + Transient | Compression multiplier for sustained + transient loads limit.
|
...
Note |
---|
These multipliers are based on psi values. |
