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. |
Shear
Values that can be used to override the defaults in the LRFD 5.7.3.3 shear equations used by the program.

Manually Define Values | Allows the user to unlock all variables in the shear calculations |
bv | Effective web width taken as the minimum web width within the depth dv as determined in LRFD Art. 5.7.2.8 |
dv | Effective shear depth as determined in LRFD Art. 5.7.2.8 |
β | Factor indicating ability of diagonally cracked concrete to transmit tension and shear as specified in LRFD Art. 5.7.3.4 |
λ | Concrete density modification factor as specified in LRFD Art. 5.4.2.8 |
θ | Angle of inclination of diagonal compressive stresses as determined in LRFD Art. 5.7.3.4 |
α | Angle of inclination of transverse reinforcement to longitudinal axis |
Pitch | Spacing of transverse reinforcement measured in a direction parallel to the longitudinal reinforcement |
λduct | Shear strength reduction factor accounting for the reduction in the shear resistance provided by the transverse reinforcement due to the presence of a grouted post-tensioning duct. 1.0 for ungrouted post-tensioning ducts |
