JKW05,
Thank you for the clarification, I was indeed asking which design method I should use (ultimate strength design or allowable stress design) to size my bolt for tension. The two load combinations I was referring to are, like you said, the reduced DL and full/increased wind load...
I have not been responsible for the entire structures design, I am solely looking sizing anchor bolts. I just didn't know which design method was the correct one to use in this situation.
Hello all,
I am in the process of designing anchor bolts for tension (the shear will be resisted by base friction), I am only looking at bolt strength, not concrete at this point. For referance I am using "Wind Loads and Anchor Bolt Design for Petrochemical Facilities". In section 3.6.1.1...
Hello all,
I'm looking for a clarification on the minimum reinforcement ratios for tied columns. I know ACI-05 10.9.1 states that the Ast for concomposite compression members shall be not less than 0.01Ag, then in the commentary I see it talks about the report of ACI committee 105 and a...
Hello all,
I have an existing block foundation which is 15ft by 7ft, not sure of the depth yet but let's assume it is 5ft deep. This footprint is fine to support the existing piece of machinery that is on it now, but it will soon be replaced, the replacement will have a larger footprint which...
Hokie66...best answer yet.
Well I guess this 111.11lb/ft^3 number will remain a mystery, since the post, I looked in the "Weights of Building Materials" chart my ASD book and it says lightweight (reinforced) concrete is anywhere from 72lb/ft^3 to 120lb/ft^3.
From that I suppose 111.11lb/ft^3...
Simple question with probably a simple answer.
I have always used the weight of reinforced concrete to be 150lb/ft^3. Although I am confident that this is a good density to use, I have a calculator that does automatic conversions and when doing a volume to density conversion it uses 111.11...
