Can anyone tell me what is the allowable bending stress in AREMA design manual? I just ordered the manual online, but have to wait for 3 to 4 days to receive it. I don't want to sit and waste my time and hopefully want to do some prelimnary calcs between now and then (I heard somebody saying it...
BigH - Sorry for double posting. Posting in here was my mistake. I was trying to get rid of this posting after another posting was on Foundation Engineering, but didn't find how to delete it. If anyone knows how to delete a posting, please let me know and I will delete it right then. Thanks!
In analyzing laterally loaded piles, how does F.S. is applied in the design? Is F.S. applied to k value in input data for P-y analysis (e.g. LPILE) or to output values (e.g. Moment or Deflection)? In addition, how much F.S. is generally used for the analysis? Thanks!

I do understand what you are talking about. However, my point is that what elements (either rock bolts or soil nails) are used at rock face, unless those are pre-loaded somehow, it is almost impossible to prevent H-pile section from being negatively influenced by bending. If so, how we can...
Thanks for all the comments!
As PEinc said, we don't have the luxury to have 3 ft of rock bench along the wall. If we did, this could have been a lot easier to work with. Basically the wall needs to be plumb from top to bottom. So, I am thinking to drill down and have soldier pile socketed about...
fattdad and InDepth, thanks for your comments
Since there are significant utility issues in upper 10 feet of the wall, DOT actually requires anchored soldier pile wall. So, soil nailing for the entire wall height is not an option for this project. Originally I have thought about the same thing...
Wouldn't the friction angle of 30 degree for full depth be too conservative? As I mentioned above, the quality of the rock is excellent (RQD value is 90~100). The upper silt layer actually has some sand in it and was classified as ML or SM depending on boring locations. I do understand the...
I am designing anchored soldier pile walls for State DOT. Their boring logs show two very distictive materials behind the wall location. Mostly 18 feet of silt (N=10+/-) is sitting on hard granite type of fresh rock. The height of the wall is about 35 feet and I am trying to use FHWA design...
The closest model I found was case 2k (outer edge free, inner edge simply supported). In my case, anchor is installed through pipe lookout welded in h-pile and 7 strand anchor head bears on the steel plate sitting on pipe lookout.
I want to know in normal practice how other engineers configure inside and outside corner piles requiring anchors? For outside corner pile, in order to eliminate use of anchors for the pile I normally use a number of straps using 4x1/2 steel bar welded on flanges of adjacent h-piles each...
I am currently working on designing a size of anchor bearing plate for 45 ft. high anchored soldier pile wall and want to get your advice on it. Initially I simply tried with a simple beam model to design the thickness of the plate, but after finishing the calcs I thought that the number I came...
Thanks for all the comments.
Sorry for not describing my problem very cleary. Yesterday I didn't have enough time to describe my problem in detail. The steel plate with 4 headed studs will be fully embedded in 24" thick reinforced concrete wall. the distance from the head of the studs to the...
Hi,
I am working on designing a simple tension connection using 4 headed studs (3/4 x 3-1/8, one on each quadrant) welded on 6 x 6 steel plate and have a question regarding the plate thickness. This connection including the plate will be fully embeded in concrete wall and a steel rod (#10...
Has anyone heard about "SupportIT" by GTSoft?
I am looking for a design software for soldier pile wall with multi rows of anchors. Additionally I want to input multi layers of soils behind the wall. It seems to me that SupportIT does all that I need and prior to making my final decision I want...
