39th progress report
I. SCOPE OF THIS REPORT In the Thirty-eighth Progress Report a series of 118 tests was reported on web crippling under concentrated loads. These 118 tests which included 17 representative tests of the Twenty-fifth Progress Report were carried out for web crippling by loads on the span, by simple end reactions, by end reactions with additional loads on top flange, and by reactions of continuous supports with similar additional loads. Two formulas were developed from the entire series of tests which represented, for the two cases (loads on span, and reactions), all test results with satisfactory accuracy. However, only 8 out of these 118 tests were carried out on single web beams (all others referred to double webs). Therefore, 20 additional tests of single web specimens reported herein are designed to furnish more evidence on single web beams.
