Section 46-2.01D(2)(b)(ii). Use for (1) ground anchors that are not designed by LRFD or (2) footing ground anchors that take seismic loading and have a lock-off load greater than or equal to 0.25FTL (0.25T for non-LRFD design).

1 and 2. Use for footing ground anchors that take seismic loading and have a lock-off load greater than or equal to 0.25FTL.

1. Use if the footing anchors that take seismic loading and have a lock-off load greater than or equal to 0.25FTL are the only ground anchors in the project. Delete par. 2.

Delete item 5 in the list in the 1st paragraph of section 46-2.01D(2)(b)(ii).

2. Use if, besides the footing anchors that take seismic loading and have a lock-off load greater than or equal to 0.25FTL, there are also other ground anchors in the project. Insert the locations of the footing anchors that take seismic loading and have a lock-off load greater than or equal to 0.25FTL. Delete par. 1.

Replace item 5 in the list in the 1st paragraph of section 46-2.01D(2)(b)(ii) with:

5.Except for the ground anchors at ______, if the movement measured from 1 to 10 minutes is greater than 0.04 inch

5.1.Hold the load constant for an additional 50 minutes.

5.2.Measure and record the anchor end movement at 15, 20, 25, 30, 45, and 60 minutes.

5.3.Plot a creep curve as a function of the logarithm of time, showing the anchor end movement from 6 to 60 minutes.

3. Use for horizontal ground anchors, such as those used in walls, when the anchors are not designed by LRFD. Edit the table if the designer requires a different maximum test load.

Replace the table titled "Loading Schedules" in section 46-2.01D(2)(b)(ii) with:

4. Use for vertical ground anchors, such as those used in footings, when the anchors are not designed by LRFD. Edit the table if the designer requires a different maximum test load.
