4- Use 12-#5 vertical bars and 25" bolt embedment.
If shear per bolt is less than 5.34 kips, do not use "B" ties.
#ANCHOR BOLT DESIGN EXAMPLE PDF HOW TO#
How to use the Standard:1- See Table-1 for base plate size and the anchor bolt hole location 2- Design anchor bolt size, base plate thickness and welding based on factored load 3- Determine shear per bolt.
