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.
