Oversized Holes in Base Plate

---

For front anchors concrete shear breakout check

Oversize hole Yes ⇨ Mode 3 is used ⇨ front anchors take
                                                              1.0 x V_u shear force
Oversize hole No ⇨  Mode 1 is used ⇨ front anchors take
                                                              0.5 x V_u shear force

If select Yes ,this means significant oversized holes are used in the
column base plate.
In concrete shear breakout check, Mode 3 is used for checking,
front anchors take 1.0 x V_u shear force. (Reference: ACI 349.2R-07
Guide to the Concrete Capacity Design (CCD) Method-Embedment
Design Examples Page 47)

If select No , this means special provisions are made to equalize
the shear force transfer from base plate to all anchor rods.
In concrete shear breakout check, Mode 1 is used for checking,
front anchors take 0.5 x V_u shear force

Select No if anchor bolt plate washers are tack welded to base plate
and anchor bolt nuts.
