I am designing a soldier pile and lagging wall adjacent to a railroad. The excavation will be about 22ft deep and to rock. The rock is grey shale with about the top 5 ft weathered. Below this, the rock is fairly competent (RQD~75%-85%), and have assumed that the pile is fixed here.
Where can...
I am currently working on the end support of a two pin steel arch, I am looking for any information in print that dicusses the design of the upper and lower shoe grillages (that is the steel grillage from the end of the arch to the pin, and from the pin to the concrete skewback or pedestal). Is...

I have a few questions:
- Are there more manufactures just than Williamsport Wire Rope?
- Is there anyone that knows or knows where I...
There is also a table in AISC's Manual of Steel Construction - Allowable Stress Design, 9th Edition and in the LRFD, 2nd Edition, which will give you the surface area per foot of various structural shapes, or you can easily calculate it by hand.
One other thing I believe that you should consider with bolted connections and tubular shapes. When torquing bolts on tubular sections, the tension in the bolt from torquing utlizing the "turn of the nut" method can actually crush the tube section. What I have done in the past is to...
Is there anyone out there with experience using Expanded Polystyrene (EPS or commonly known as styrofoam)as the "filler" in compensated foundations.
I am considering using EPS beneath a bridge foundation in a location where the soil conditions are very poor. Soil borings taken...
I suppose that I should ask the question. Is this a truss for a highway bridge or for a building?
If this is a truss for a highway bridge or a very dynamically loaded structure, I would be very leary of welding gusset plates to diagonals and chords. This is because the welds that are in areas...
