This Mathcad worksheet was submitted by Eva Landsoght (NL) who is currently writing her Ph.D. thesis at Delft University of Technology.
The worksheet was created in Mathcad 14.0 and shows a calculation of beam shear and punching shear strength of a concrete slab according to Eurocode 2 (EN 1992-1-1:2005).
A short interview with Eva is available in our "Meet the Mathcad Users" series on the Mathcad Blog. Take a look, she may even have a tip to share
