32nd progress report
I. SCOPE OF THIS REPORT (1) Ten tests were conducted on the following beams (a) 18 - 1/2 -14, 2, and 3; and 16- 1/2 - 2. These are the last tests of the original series of beams. Specimens 16- 1/2 - 1 and 3 after welding showed bad distortions in shape and for this reason could not be used. (b) In order to supplement the tests, six more beams with unstiffened flanges were tested. For three of these beams left over studs of the old stud tests were used. These beams are 4 in. deep and are designated as 16 -1 -1 , 2, 3, (4"). Three more beams were spot welded in our shop from left over plate elements of the stud investigation and are designated as 16 - 1 1/2 - 1, 2, 3, (4"). it was considered desirable to make these additional tests for the following two reasons: (a) The dimensions of these beams are of the kind most likely to be used in practice, whereas many of the other beams proved too wide for practical application; (b) all other beams were 8 in. deep and therefore it seemed desirable to include beams of a different depth. These tests conclude the series with unstiffened flanges. (2) Parallel with the tests further work was done on the final evaluation of the entire series. This work is now completed and recommendations for design specifications are being worked out. The results of this evaluation and the corresponding recommendations will be communicated shortly.
