Hillerborg Strip Method
Hillerborg Strip Method
(OP)
Hey,
Can anybody tell me if the hillerborg strip method is appropriate for designing a basement wall fixed at the ends and base and free at the top. im assuming that moment is taken by the base from a triangle (inclined at 30 degrees) at the bottom of the wall..Thanks!

RE: Hillerborg Strip Method
I wouldn't use the strip method except for slabs of an irregular shape. You should look after this textbook: "Tables for Analysis of Plates, Slabs and Diaphragms based on the Elastic Theory" by Richard Bares. There you can find the moment, shear and deformation for typical cases. Attached you can find your case. Regards,

Your table is for 3 sides fixed.

Meaby I missunderstood, but Sasas2 wrote: "basement wall fixed at the ends and base and free at the top". I thought he meant 3 sides fixed and the other free.

I believe the Hillerborg strip method is a good method to use. You could use Yield Line Theory too, but Hillerborg is probably more conservative.

I think your are right. In which case the Nilson concrete book has the 3 sides fixed and 1 free edge loading diagram.

I would be caution about considering the base of the wall as being fixed. That would have to presume that the footing will not rotate - how much rotation will effectively negate any fixity you think you may have?
