Pylon sign board foundation design
Pylon sign board foundation design
(OP)
Hi,
I am asked to check the foundation stability of a pylon sign board of height 2000mm, 900mm width and 160mm thickness made of mild steel. The structure is in the middle east with a wind velocity considered around 60m/s. I have been trying to search only for the footing design of pylon sign boards and can only find boards erected on posts. Also I need to know how to calculate the design load and moment of such a structure standing directly on the ground. They usually follow the BS or ACI code here in the UAE. Thanks in advance.

It looks like this

It is connected to the footing with base plates and anchor bolts. I cant find any design details for such a structure, hence I'm lost..

I think that I see now what you are trying to analyze. Your posts have to have rigid, moment-carrying type bases to transmit the overturning moment and the base shear to either a spread footing, or a pair of drilled shafts. The drilled shafts would obviously be similar to an embedded post design, with the additional step of designing the base to transmit the loads. Since that approach apparently doesn't seem to fit your situation, I am guessing that you have a moment-resisting type of spread footing. This would then be a combined footing supporting both posts. You can treat the design of such a moment-resisting footing just as you would one designed for a building column with moment - and paying attention to the base plate design to ensure it can handle the moment carried to the footing.
Good luck, Dave

But doesnt the wind loads acting on it make it more complicated? I checked the wind load manual calculations..which seemed quite complicated to do by hand
