Use Lagging: | Check this box if lagging is to be considered between piles. |
Lagging Depth, ft: | Depth below grade at which lagging pressure is to be calculated based on the active soil pressure. |
Lagging Pressure @ Depth, psf: | Pressure used in the design of horizontal wood lagging between piles. |
Lagging Moment @ Depth, ft-lbs: | Moment computed assuming arching action and using moment = 0.8 * wl2/8. |
Lagging Shear @ Depth, lb/vertical ft: | Shear computed using wl/2 where w is the Lagging Pressure @ Depth determined above. |
Lagging selection: | Wood lagging selection, such as 4 in x 12 in. No design is performed based on this entry, but it is printed in the calculation report for documentation purposes. |
