Shear in concrete slabs having concentrated loads close to supports
In our column for 19 December, Mr R. N. Morgan asked whether other of our readers were aware of published works giving elastic influence coefficients for shear forces in plates due to loads close to supports. We have received a response to Mr Morgan's request from Von Dipl.- Ing. Bjorn Vik of Sandvika in Norway:
I believe there are some answers to Mr Morgan’s question about shear in concrete slabs. He mentions Pucher’s book, in which unfortunately the influence fields for shear forces were seriously in error. However, in the book Platten und Behalter, by E. Bittner (Springer-Verlag 1965) several correct influence fields are presented. Also a
paper by the writer, in Bauingenieur, 1964/12, deals with shear forces from loads in the vicinity of the support.
