Ulitmate load to use for Anchor bolt check ACI - Ap. D
Ulitmate load to use for Anchor bolt check ACI - Ap. D
(OP)
I have 25k uplift and 9.5k shear loas based on allowable strees method.
To check Appendix D ACI. I need to convert these to Ultimate loads (Nua and Vua), may I ask what above number has to be multiplied to so I can get correct value for Nua and Vua?
Thank you

These are the values I got from the drawings of a structure built 1954.
There was no break out of the numbers to tell me how much of it was what kind of load.
My assumption is the Uplift is due to wind load as well as shear.
So what will be the multipliers?
Is it wrong that I multiply Uplift by 0.9 and Shear by 0.85?(Vu=0.85Vn and Tu=0.9Tn)
Sorry my knowldge in this area is bit rusty. I appreciate the direction.
Thank you

so am I right the Tn and Vn are factored loads?
So there is difference between factor load and ultimate load?

Loads are factored up from service levels - for your unknown mix of dead, live, wind, etc. I'd use 1.5 to 1.6.
