I'm Working on checking the sliding for a retaining structure that is in a high seismic zone and I have issue with the sliding. Tried to add shear key but thigs get worse because after adding the key, both passive and (active, surcharge and seismic earth pressure) increased, but the increases of...
Should we add the seismic forces due to own weight of seismic structure (Eh and Ev) to the dynamic seismic earth pressure force when we check the stability, especially if the own weight is significant? The used method for determining the dynamic seismic earth pressure is Mononobe-Okabe. Any good...
Yes it is. Good point! but what if the pole cannot resist the moment and I need the help of concrete? I still will need to design that hollow concrete section for flexure and shear.
Thanks everyone. Actually the case that I was talking about is for cast in place hollow reinforced concrete section that is subjected to mainly flexure and shear (axial is small) similar to the attachment. IF anyone knows a reference or example for such case that would be appreciated...
Hello,
Does anyone know a good reference and examples that explain how can a hollow reinforced concrete beam section(rectangular or circular)that is subjected to flexure and shear be designed? Does ACI address this kind of beam at all?
Thanks!
Hi everyone, just trying to know when shall I use Alignment Chart vs. using the approximate values of effective length factor K shown in AICS table C-A-7.1? Appreciate your answer.
Thanks,
I got a response from SINE Wall and do the design for their patent system ,however the global stability shall be done by the EOR. My question is that the common design procedure? so the prime designer has do do the performance design and the actual design shall be done by the manufacturer?
Hello Everyone,
Just received a project where several types of wall will be used. One of the walls is conventional (standard) MSE. Would like to clarify, who shall provide the design of the concrete panel in terms of the thickness and reinforcement? Also, who should design the steel strip...
Thank you oldestguy,chicopee and OldBldgGuy for your responses. The project has a limited budget,so it will be hard using bubbler system . Also the concern of using the sleeve, poly pipe, epoxy coating,... that the uplift force will be reduced, however the reduction cannot be quantified, so I'm...
Hi Everyone,
I have a project in lake Michigan and it’s basically a marine dock fixed on piles in lake Michigan. I’m trying to calculate the uplift force on the piles due to the ice. The historical ice thickness is 30”, pile dia. is 12”, pile height above the lake bed is 14’ and it has an...
