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" …

CCFSS Library (1939 - present)

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 …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

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 …

Coordination Of Transportation Systems Of The United States, Herman Blickensderfer

Masters Theses

"To any thinking man it must be apparent that the railroads are of vital necessity to the country at large as they can more cheaply move a host of the heavy commodities than can the trucks, and of course the waterways do not and cannot reach every part of the vast territory that must be served. On the other hand it is equally apparent that many of the other types of traffic can be handled more readily and cheaply by truck than by rail. This would lead one to conclude that some way should be found to give to each …

Hydrography Of The Larger Springs Of The Ozark Region Of Missouri, Warwick Lewis Doll

Professional Degree Theses

"This thesis is based upon a study of the larger springs of the Ozark Region of Missouri and is designed to answer many requests for information about the large springs.

Special studies were made to determine the probable location and approximate area of the drainage areas of the large springs (previous writers have referred to the drainage areas as being “very large" or "enormous", apparently, without any very definite idea as to the extent or the drainage areas). The average run-off per square mile from the assumed drainage area, herein called the "spring factor", was determined for the largest springs. …

An Approach To County Planning - Miller County, Frederick William Hurd

Professional Degree Theses

"The purpose of this report is to present and discuss a proposed eight year state and county highway program as applicable to Miller County. Local needs for transportation service may be most readily and efficiently administered to on the county basis. The highway requirements of the state are now largely for local service roads and it is evident that a fair and just method of allocating this service must provide for the physical characteristics, economical status and local peculiarities of the area involved. We may therefore justly assume that the counties, the smallest political subdivisions in the state having direct …
