Thanks for the response Retrograde. My approach would be to ignore the center bar when designing for compressive loads as well. However, even if the center bar is ignored for design, it is still present in the pile, and will attract compressive load purely due to the relative stiffness between...
Hello,
For a CFA pile designed as end-bearing on rock, is a full rebar cage necessary for the full length of the pile or is it okay to use the typical CFA reinforcement scheme of a full cage in the upper 1/3 of the pile and only extending a full-length center bar to the bottom of the pile?
Is...
I think only one document got uploaded in my last post, here is the other document.https://files.engineering.com/getfile.aspx?folder=1efbbbe3-f458-463e-9738-8a87b8679916&file=TP-1.pdf
Info for two different load tests on the same site are attached. Subsurface conditions are only provided for test pile #2 but conditions are relatively uniform throughout the site. 6 vibrating wire sister bar strain gauges (GEOKON) were used for each test pile, equally spaced along the depth...
Hello,
I used strain gauges on two recent CFA pile jobs. This was my first time using strain gauges. Upon converting the strain gauge data into loads and plotting my load vs depth graph, something seems off with the data. The lines on my graph "zig-zag" down the depth of the pile which...
Hello,
Does anyone have any good references for the design of a reinforced concrete retaining wall with buttresses, and specifically, the design of the buttress itself. I have found a couple references for design of couterforts but can't seem to find anything about designing buttresses.
Thanks!
