Extract

Professor koiter, in his note (January 1954 Journal) states that I (April 1953 Journal) was “ apparently unaware” of Weber's two papers on the subject, published in 1924 and 1926. I was aware of the papers, having cited them in the bulletin by Seely, Putnam and Schwalbe on “The Torsional Effect of Transverse Bending Loads on Channel Beams.“

Some references in addition to those already cited may be of interest. The unorthodox behaviour of a channel beam in bending was observed and reported by C. Bach in 1909–1910. A. and L. Foppl wrote a section on the “Schubmittelpunkt” in their book “Drang und Zwang.“
