Hello everyone,
I have flat slab and the columns are not symmetrically placed. I am calculating punching shear acc. to Euro code and German national Anex. There are Beta factors give by Eurocode for symmetrically loaded supports and adjacent span less than 25%. But the there is also an option to calculate using plastic shear stress distribution (DIN EN 1992-1-1/NA:2011-01 , NCI Zu 6.4.3 (3)). In the formula, the moment is give for moment at the column. My question is, if we have a column with m hinge at the top, in my case the columns take only axial load and bracing are taken by core and shear walls. in that case does the method of plastic shear stress distribution can be used? or is it valid only when we have fixed end column ?
Thank you!
Simon
