Wingwall contribution to resisting overturning
Wingwall contribution to resisting overturning
(OP)
Hi,
I am checking the substructure design of a skew bridge with wing walls at varying angles to the abutments. I understand that the wing walls help to resist the overturning moment, but I am unsure of the calculations for this effect. What area of the wing wall should be considered and where is the moment arm taken from? Is it best to disregard them all together, or is that assumption too conservative?
Thank you

Easiest to ignore them to start, and then add their affects only if needed.
