Typically when we receive friction values and passive pressures from the geotechnical engineer they will either specify whether the values are ultimate or have a FS of 1.5. Assuming the values have the factor of safety in it, when you are designing the footing for sliding would you increase the...
We have a client who is changing an existing sign. Problem is with the new wind loads the cantilevered (single pole) 24" pipe no longer works. Is there a way to strengthen it? Thinking about looking into solid grouting the core, just dont know if thats standard practice, do's vs don'ts.. Thanks
Does the 10kip load in AASHTO only apply to traffic barriers on bridges and atop retaining walls? I am designing a barrier at bus stops.... There is no way that designing it for impact loads based off of speed and vehicle weight will be financially feasible.
What category do surchages fall under in the IBC load combinations? If you have a strip surcharge from a building, do you split the dead and live loads up or would the resulting load applied to the retaining wall be H? IBC 1610.1 "Design lateral pressure from surcharge loads shall be added to...
How would you reinforce a caisson footing (about 5'-0" deep) with a partially embedded cantilvered column? We feel its not a pile so the stuff in Section 18 of the IBC does not apply but nor does anything from the ACI. We want to treat it like a beam and reinforce it that way. What do you think?
Anyone done this before? We don't want to extend the column to the bottom of the footing but need a way to calculate how the moment in the column dissipates in the footing relative to the embedment and how to reinforce the remaining concrete if needed. Thought of subtracting the resulant from...
