This is friendly competition on how to calculate the at rest earth pressure coefficient for a given wall/soil scenario. Details are shown on the link below. Ends in couple of weeks.

I am working on a drilled pier design software. I would like to add torsional resistance and am very interested in the different equations and approcahes used worldwide. The program already has axial downward, uplift, lateral and moment loads. In addition it will have reinforcement design per...
There is a one level anchor drilled pier shored wall near a property line. Tieback anchors and Deadman anchors are not possible due to being outside the property line. Using another drilled pier as an anchor which derives its capacity from skin friction below failure plane is an option...
What used to take hours to analyze can now be done in minutes. When you have a vertical single pile loaded with a moment and shear loads, the problem can readily be solved. The pile could be in a pinned or fixed condition at the top of the ground. However, when we have multiple soil layers...
I noticed IBC 2009 is requiring active earth pressure be applied to the keyway in addition to passive resistance (last sentence of 1807.2.1). Any thoughts from retaining wall designers on this topic? This was not in IBC 2006 or 2003.
I have a spreadsheet that can now only do cantilever retaining wall. I would like to add option for CMU stem or combination of concrete and cmu stems (up to 3 sections). I also want to add an option for top restraint. What references would give the equations and theory I need? Thank you.
I sometimes encounter a shallow foundation that has a finite layer of suitable soil below it and then underlain by soft Clay. I am trying to use the Boussinesq equations to generate footing stress contours in color beneath the footing. This way, I can see the stress at the top of the soft clay...
I have a friend helping me with a VB application. We are stuck at getting an installer routine for the program and some sort of copy protection. The program was created from an excel spreadsheet. We intend to sell it and need professional installer and copy protection suggestions. Thanks.
A retiring engineer has decided to close his business. I became aware of it at the last minute. If we were to come to an agreement and once the original owner has retired (few weeks to go), could I realistically inherit his clientele? It is very small practice and I have never been affiliated...
I am looking into "The Business of Design Consulting" course offered by ACEC. Looks like a neat 4 day class. I would be very interested to hear from past attendants. Thanks.
Can someone refer me to a pipe piles publication or post it here. I have a small project and want to propose open ended pipe piles. Loads are moderate but client is insisting on driven pile foundations. Thank you.
Anyone have access to to ACFD SRA/Rural Fire Access Manual? I have a project with a 65k fire truck on stiff Clay. I can do the pavement thickness design but am stuck at the ACFD manual requirements.
I have recently come across some soldier beam design calculations near a 3 story building.(7 ft away) The surcharge is approximately 1,000 psf for the width of the building. The shoring height is approxmately 12 ft and they used a cantilever section.
My question is: So far I have been...
I have a site with CH soils with qu > 5 ksf, SPT > 20, and have given recommendations of 18 inch piers embedded 12 ft into the ground. Loading is approx. 3 kips vertical, 6 k horizontal & 14 k-ft moment. It is supporting 8 ft high panel. It is an individual pier and not a group.
Now I am...
