16mm J bolts & metal plates

[2204z]

Usually.. can you use 4 pcs of 16 mm j bolts embedded 8 inches inside the concrete column where you can attach metal plates on top to support I-beam rafters above it? How do you compute if the 4 pcs of 16mm bolts can take the shear from the wind?

 

[TLHS]

J-bolts generally aren't recommended much anymore if there's any reasonable uplift. They can bend and pull out. If you're in the US you want ACI 318, Appendix D. You also want someone who knows how this works to help you through it or review your work.
