Wingwall question
Wingwall question
(OP)
I have to decide about the angle for a wing wall. What impact the angle has in design?
I have seen 30 degrees, 45, 60 and sometimes even the wing wall is perfectly perpendicular to the head wall?
My case is a 10 foot head wall which I have no clue what angle do I use for wings?
Also anyone knows how I connect the wing to headwall?
I appreciate your direction and information. This is not a bridge abutment wing wall. It is only for purpose of holding soil behind so there is no road or bridge around.
Sincerely,
BFstr





RE: Wingwall question
The variety of wingwall designs can be adscribed as well to aesthetics as much as to function, since it doesn't use to be considered a particularly expensive item in the related designs, and usually that is what I would propose to someone like you when all the engineering requirements are understood have been (or will be) met.
RE: Wingwall question
The angle used is a function of the level of stability needed for overturning and sliding, plus aesthetics (blending with existing contours) as previously mentioned.
Thewre is no magic or one answer here.

RE: Wingwall question
Dear msquared48 (Structural) or Mr. McCann thanks for your comment but you mentioned that wings help to stability of wall. As I remember I designed headwall separtely and wingwall separetely, I didnot analyze the whole thing for overturning stability, well if I knew that I have to still didn't know how? Can you please explain it more. I love to learn thid
Thanks,

RE: Wingwall question
Personally, I try to make them a single unit if possible though. You did nothing wrong here so long as it is stable structurally.

Another function is to protect the backfill against scour and to provide gradual transitional flow("inlet contraction flow" and "outlet expansion flow").Here your hydraulics(e.g. flow rate and velocity) should have been critical in deciding the Wwll flare angle.
