Let me know if my understanding is correct. Assuming the anchor is prestressed by X by torque ( unknown here) and then by subjecting it to max pressures, we'll come to know net stress to reach yield strength fy. We know the actual yield strength of the rod. So fy-y should let us the prestress...
Exactly! I guess they didn't tension it.
From all the limited conversations I've been to they've tightened the bolt. That's it. They have the cell pressure from the system and are telling that the bolts were applied torque until the cell pressure has reached the maximum and started dropping...
Thanks for sharing. I believe their statements are limited to certain conditions. Currently, we have asked the contractor to confirm the preload that's applicable for the ground anchor after accounting for all losses. I'm pretty much sure they are going to put it in bolt torque and clamping...
Hello Everyone!
For an anchored sheet pile wall (say 9m height), prestresses strands with a preload of 15T were recommended to limit deflection. Bridge abutment behind the sheet pile wall.
However, during execution, contractor has replaced strands with micropiles (fy 500 to 600 MPa). We've...

We are currently working on a proposal. Following is the overall scope
1. The Pilecap (PC) supports the bearing from a bridge spanning across a navigation channel
2. The PC is supported on ground with continuous sheet pile at front for retaining the soil and fill behind and few rear piles
3...
Sorry for late response. Design methodology for LRFD is clear. Why I asked for any closed section example is.... The proposed sheet pile is subjected to substantial vertical load from bridge bearing as well. If you look at Eurocodes, we have clear limitation on thickness for a cross section and...
The above-mentioned figures indicate the force distribution and criteria for evaluating the embedment depth. Basically, geotechnical aspects, I believe. Section 11.8 indicates forces to be considered for structural checks. I'm looking at evaluating the structural capacity (utilization ratio)...
Hello everyone!
Does anyone here have worked out example for design of flexural members with box section? I've prepared the design calculations based on the standard but couldn't get any solid examples for box sections. Lot of examples on I section are there. I need something to validate my...
Hi Everyone,
Often, we design our structures with material grades corresponding to one grade pertaining to one standard and during construction, depending on availability, equivalent grade pertaining to other standards are selected. From EN standards to ASTM standards or vice versa. Mostly key...
Hi HTURKAK
Actually, I posted this in another thread and got responses as well. Thought of linking but the thread seems deleted.
Anyway, Thanks for your response.
Batter pile construction is ruled out siting difficulties in positioning and driving.
Rock anchor may be provided, depends on...
