Dear Sirs,
I am working on the design of an incrementally launched box girder bridge whose parameters are as follows:
2Nos. End spans 26.5 m each.
4 Nos. Internal Spans 46.5 m each.
All bearings are laminated elastomeric after launching. During the launching Teflon bearings are used to minimize...
May I request for some advise on a pile design?
I have a case where 3m of earth filling is coming below the pile head. (Abutment)
On the right side the gravel fill extend to a long distance horizintally. On the left side earth is sloping towards the river at 1:1.5 (vert:horz.)
Pile diameter 1.4...

Dear Sir, Your first suggestion was perfect. In my
re-analysis I found the error that I had fixed bearings
in the X-direction. When they are released the statics
are tallying perfectly and reactions are much lower.
The high value of Hz forces was not coming from BS codes.
Now I have no...

Dear Sir, Thank you very much for giving me a guidance on
this subject. The reason I am getting a high horizontal force is that the tractive forces accoding to BS codes.
This is an arch bridge. Span 37.5 m, Width 10.4 m
My LB bearings (4 Nos) are fixed in the direction of...

I have a bridge with 4 elastomeric bearing pads on the
left bank with movement restricted along the axis of
bridge. The Service Horizontal force on one bearing
is 2300 kN (Max),Laminated Bearing Pad is 700mm x 600 mm x 83 mm thick.
