Hi there,
As per the subject line, I am looking to replace a footbridge deck with a temporary decking system (thinking GRP grating panels?) but struggling to think of sensible options of making connections into the pre-stressed concrete girders as decking is at the bottom of the section so...
Hi,
I have read thread256-285800 and got stuck here:
"If you look at Bowles Table 9-1, modulus subgrade, kv (kN/m3)
approx equal to 240 Cu (kPa).
Allowable bearing pressure, qa (kPa) = Nc Cu / SF = (5.14 /3) Cu..."
Bowles Table 9-1 shows ks (not kv), and there is no Cu there...
Also, where is...
Hi,
I am struggling to find a filler beam design example for a road bridge - if you happen to have one handy and were willing to share that would be much appreciated.
Thank you.
Hi there,
I would like to ask your help to try in this thread to collate standard bridge details from around the globe and also any good v. bad practice guides, etc. especially for the most common types of bridges, but also any "by exception" non-standard solutions - if you could paste your...
Hi,
How do I work out the horizontal and vertical moduli of sub-grade reaction, for laterally and vertically loaded piles in clay?
I want to apply the sub-grade reaction values in a model (using Winkler springs) as I need to confirm the pile moments for the design of reinforcement in piles...
Hi there,
Take a small bridge made up of regular precast concrete box culvert units plus irregular end units with wing walls, apron, etc.
Unfortunately, no specific details were supplied what level of detail was required - I am treating it as an overall rough check of the key elements and...
Hi,
I wanted to get a quick second opinion on the following. I am specifying uniformly loaded beams and plates bolted on both ends to rigid supports and have used the conservative simply supported scenario to get the midspan bending moments (and reactions at supports) as per sketch. Now, for...

Hi,
This could be a continuation of the thread referenced above. I am wondering how the OP managed his design? I am in a similar situation, where I need to come u with a solution of securing roof avers and wooden panels resulting from wind roof uplift forces up to -70psf. This...
All the best in the New Year from a new member!
New Year's Day - resolutions, ahh... ;-)... so I thought I'd ask for advise about the following:
I currently work and live in the SW of England where strangely, given the current economic climate, there seem to exist some job openings in the aero...
