I am trying to design a 300mm Diam. through-bolt which penetrates through 200mm THK reinforced concrete wall and it is under both axial and shear force. The checks that I am trying to apply are as follows:
1-Concrete bearing capacity ----> not sure how to calculate it for a through-bolt? what is the effective bearing length, I've to assume?
2-Punching shear (axial force in bolt generates a pull out force that tends to punch through wall)
3-shear capacity of bolt
I appreciate that if you can help me.
