SCOPE OF THIS REPORT all the beams heretofore tested in this program were furnished with web stiffeners in order to aviod crushing of the web at the load points and at the supports. In practical application the use of such stiffeners at points of concentrated loads would not only be uneconomical but also would impair the versatility of the elements, since stiffeners would have to be spaced on each individual beam according to the particular location and loading. For this reason it seem essential to investigate the resistance of unreinforced webs to concentrated loading. The tests reported herein are to …

I. SCOPE OF THIS REPORT In the 12th Report, Section III, a method was proposed for the determination of the required strength of collateral attachments. In addition, a test procedure was suggested to test the validity of the theoretical considerations on which this determination was based. In the present report two more formulae are developed which will serve for the experimental verification of this approach. Preparations for these tests are now under way.

1. SCOPE OF THIS REPORT Failure tests have been carried out on beams 0-3, P-3/Q-3, I-1, I-2, I-3, H-1, H-2, H-3, and K-1. As mentioned in the Sixteenth Progress Report (p. 15) it was, anticipated that beams H,I,K, as originally designed, would fail in pure yielding. Since such a failure is not revealing for this investigation, an attempt was made to narrow both flanges of these beams. This work was done in the shops of the School of Civil Engineering and of the School of Mechanical Engineering. It turned out, however, that in cutting off parts of the flanges, the …

I. SCOPE OF THIS REPORT Failure tests on two specimens each of beam type A, B, C, D, E, F, G, have been carried out. The lengthy final evaluation of the results will be given in a later report. However, the results of the tests reported herein allow the drawing of rather definite conclusions.

I. SCOPE OF THIS REPORT In the preceding 14th Progress Report a method was proposed to determine the forces acting in the welds in the web of I-beams composed of two channels. This method essentially has been based on the magnitude "e", the distance of the flexural center from the axis of the web. A formula for "e" was given which applies to symmetrical channels of uniform thickness. In the present report this expression for "e" will be simplified and a more general expression will be derived for "e" for symmetrical channels with web thickness differing from flange thickness. Furthermore, …

I SCOPE OF THIS REPORT It has been mentioned repeatedly in previous Reports that the spot welds in the web joining the two parts of the beam tended to pull apart at the supports. It is therefore obvious that, in order to properly design such beams, this fact must be taken into consideration. The present report undertakes to give an analysis of this behavior and to stipulate certain requirements with respect to these welds (strength, spacing) which have to be met in order that such failures may be excluded. The present analysis pertains only to beams made up of two …

I. SCOPE OF THIS REPORT At the present time failure tests are being carried out on the 24 beams series D and E. To date the following beams have been tested: D-18-16-816a and E-18-16-816a and b; E-18-14-816a and b; D-18-14-816a and b; E-18-12-816b; D-18-816a and b; E-18-18-88a and b; total - 13 beams. The failure tests on those beams are carried out in a way different from data used heretofore (see section II of the report). As a result very extensive data are obtained for each of these beams. Since the evaluation of these data will require considerable time it …

I. SCOPE OF THIS REPORT 1. A.stress investigation has been made on beam E-18-12-816 b at the load points with 6 and 12 ft. span and center load and with 12 ft. span and quarter point load. 2. The results of these tests seem to show that, after the completion of similar tests on two more beams of the present shipment enough data will have been gathered to answer the question of stress distribution. It was therefore thought advisable to carry out a more complete investigation on this beam. For this purpose the stress distribution at five additional cross sections …

I. IDENTIFICATION OF SPECIMENS. The method of designation used hitherto is not sufficiently differentiated to identify the present and future specimens since specimens with identical bottom flanges but different top flanges are used. For this reason from now on each specimen is designated by symbols and figures, for example D-18-16-88a in which: D designates a series of beams, 18 designates the gage of mterial used for web and bottom flange, 16 designates the gage of material used for the top flange, 8 designates the depth of the section in inches, 8 designates the width of the bottom flange in inches, …

Report On Tests Of Fenestra 1 1/2" Roof Deck Used In Horizontally Loaded Diaphragms, Authur Wilson, George Winter
CCFSS Library (1939 - present)
INTRODUCTION Increasing interest in recent years in the performance of roof systems acting as shear diaphragms to resist horizontally applied loads, as well as the vertical loads for which they are primarily designed, has led to an increasingly large number of tests of fullsize and scaled structures loaded in this manner. Fenestra, Inc., manufacturers of light gage steel floor and roof panels, has sponsored an extensive series of tests at Cornell University of floor and roof diaphragms composed of certain of their standard panel sections. The following report describes tests of shear diaphragms using three types of Fenestra 1 1/2" …

I. OBJECT OF THIS REPORT The full program of tests outlined at the meeting of the Technical Subcommittee held in Ithaca on June 12 has been carried out with one exception: due to the limited time it has not been possible to determine the modulus of elasticity of the sheets. However since the modulus of elasticity of steel under any circumstances is about 29,000,000 to 30,000,000 p.s.i. this point of the program has no immediate practical significance. The following tests have been carried out: 1. Tests to failure of the remaining specimens of the series B - 22. 2. Determination …

I. OBJECT OF THIS REPORT Buckling tests have been carried out on the remaining three beams of the 22 gage series, i.e. B-22-812a, B-22-816a and B-22-820a. A stress survey has been made on the bottom flange of beam B-22-812b. A new series of 22 gage specimens has been designed for the further study of the bottom flange stresses and of the top flange buckling.

I. OBJECT OF THIS REPORT Since the investigations discussed in the previous report have proved that the stress distribution at midspan was fairly uniform in the narrowest, medium and widest beams of the 14 gage series, it seemed unnecessary to carry out investigations on the remaining two intermediate beams A-14-66 and A-l4-610. Three beams of the 22 gage series have been investigated so far, namely B-22-84a and b and B-22-88a. Detailed stress distribution surveys have been carried out at midspan on beams B-22-84b and B-22-88a. It was impossible to carry out such a survey on beam B-22-84a, since this beam …

I. OBJECT OF THIS REPORT After having obtained preliminary information from the abbreviated tests referred to in the previous report, a detailed survey of the stress distribution over the bottom flange at midspan has been carried out for the beams A-14-612b, A-14-612a and A-14-68a (in chronological order). Furthermore a special investigation has been made at the same section of beam A-14-612a for the purpose of determining the accuracy of the actual strain measurements.
