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.
To maintain fixity in the required direction I need 2 stainless steel dowel pins each of diameter 110 mm
with an additional rubber cap. The dowel us secured to the
masonry plate. The pins are 1200 mm long, approx. 600 in the pile cap and 600 in the bridge beam.
The diameter and length arrived at considering tensile
strength of the pin and bearing against concrete
My questions are " Is this a feasible solution or an odd design? Is there a better arrangement?
I shall thank an expert to express his opinion so that
I can improve my design. I feel 2 Nos 110 mm dia pins
are somewhat bulky.
With kind regards!
