The walls are side by side with an existing slab below.
I found the bond strength in Hilti's tech guide and used equilibruim for rebar at T - bond force = 0; where the bond force = (pi)*d(b)*l(d)*bond strength(psi) and T = (pi)*d(b)^2*fy/4. I got a development length of about 16". It is at...
I am doweling in rebar from an existing wall to a new wall and from a new wall to the existing slab. The wall is loaded axially in compression at the top and has a soil and surcharge load from one side. Therefore, the old to new wall rebar dowels are subjected to shear forces. The new wall to...
I am designing a multi-cell rectangular tank. The cell sizes are 6'W x 7'L x 5'H and 6'W x 2.5'L x 5'H. Every reference I can find discusses how to design the multi-cell tanks, assuming the cells are symmetrical. Can anyone provide guidance on how to approach this design?
I am working on a detail for a sheet pile wall repair. I plan on placing a new sheet pile section against an existing sheet pile section in the location of deterioration and filling the openings or bellies with tremie concrete and granular material. We expect a significant bow in the existing...
In my case, this is a conceptual study where we are analyzing three options and presenting them to the client with the advantages and disadvantages of each option along with a cost estimate for each. The other two options would be a prepared surface without a ringwall, and a foundation...
I am designing a ringwall for a steel tank. The tank is 110 ft in diameter and 45 ft high, filled with liquid asphalt. I am trying to determine my bearing pressure below to size the ringwall width. I am assuming that the weight of liquid resting directly on the ground goes into the ground and...
Thanks. I don't have access to that standard. I know it is located in AASHTO Standard Specifications of Highway Signs, Luminaires, and Traffic Signals, but I don't have access to that manual either.
