Investigation Of Continuous Beams With Varying Moment Of Inertia By The Method Of Conjugate Points, Russell Arthur Bryant

Professional Degree Theses

"This design represents the application to a practical example of a rapid and direct graphic solution of the relation expressed by the Theorem of Three Moments. This method for obtaining moments in continuous beams eliminates the necessity of using arbitrary coefficients and gives the engineer an opportunity to exercise his ingeniuty [sic] and judgment toward obtaining efficiency and economy. The use of prescribed coefficients for continuous beams makes the design mechanical and unscientific and results in moments which may be 50% too small or 60% too large"--Introduction, leaf 1.

Professional Degree Theses

"Herein following is a thesis on the West Side Sewage Treatment Works of the Sanitary District of Chicago. I have endeavored to cover a large field in one thesis, but think is giving the material I have, the fundamental points have been covered. The local need of sewage treatment is so involved with county, state, Federal, and even International issues that to write solely of local conditions would be to leave out the main part of the story.

The North Side Sewage Treatment Works Of The Chicago Sanitary District, Floyd Allen Gerard

Professional Degree Theses

"My aim in writing this thesis has been to give a clear and concise picture of the Plant, its construction, operating experiences, results and the need for sewage treatment. For this reason, I have incorporated much information, which, while not dealing directly with the subject in hand, is closely allied to it and forms a very necessary background. As the Sanitary District considers its actual operating results confidential, I have refrained from including them. Much useful information can be derived from a careful study of the photographs and drawings included"--page ii.

A Few Notes From The Sanitary Engineering Field, Ronald Davies Ward

Professional Degree Theses

"This paper, it is felt, may appear to be a somewhat disconnected discussion of a few points that have come to the writer's attention from his limited experience and practice in the field of Sanitary Engineering. It has not been the intention, however, to provide a discussion of continuity which would take the reader from the ground up through the process involved in the design and construction of any particular structure, system, or plant; but rather is it to be considered the writer's attempt - although probably a somewhat feeble one - to set forth in a note-book, as it …

Diversion Of Mississippi Flood Water As Aid To Flood Control, R. W. Campbell

Professional Degree Theses

"For many years the lower Mississippi River valley has been in constant danger from high water causing disastrous floods. The important city of New Orleans, our typical French city, is below the surface of the Mississippi River at all stages, and its only means of protection at present is by a levee. Should this bulkwark give way, the whole of that city would be submerged. With this danger in mind, the writer has undertaken a study for, and design of a spillway above the city to reduce the danger caused by high water. Each year flood heights increase and the …

The Analysis Of Stresses And Design Of Multiple-Arch Dam, Guy Robert Scott

Bachelors Theses

"The so-termed: "Multiple", or "Scallop-Arched" dam, as its name implies, is one composed of a series of arches, either semi-circular or segmental in plan. These arches were first vertical but were later inclined downstream, when the engineers recognized the value of the weight of water in increasing the resisting moment. The thrust of these arches, due to the water pressure and the weight of the arch itself, is transmitted directly to the buttresses. There are numerous advantages to this type of dam over that of the gravity type"--Introduction, page 1.

Preliminary Study Of Possible Power Development On The Gasconade River, Charles Russell Barnard, Ronald Blair Wills, Harry Wesley Zieseniss

Bachelors Theses

"The location of a possible dam site on the Gasconade River as a thesis proved to be a very interesting subject. Our first trip pointed out to us that we had undertaken a large task. We also realized that our subject was too big to complete thouroughly sic in the time alloted. Due to this circumstance we tried to cover the essential facts and to eliminate as much of the detail work as possible. For instance, we made no attempt to make a complete survey of the basin, instead, we ran surveys for some distance up the river to give …

Some Typical Bridges For Logging Railroad Construction, Frederick Hauenstein

Professional Degree Theses

"In some of the pine regions of the Ozark Mountains, a considerable portion of the country is rolling and rough, comprising a succession of hills and hollows. The most efficient method of logging such a tract is obtained by locating the logging road so as to secure a down grade haul for the logs, with consequent up grade return for the empty cars. This necessitates locating the main line of the railroad along the principal creek, and then laying spurs up the different tributary creeks as they are met. Such a procedure requires much crossing and re-crossing of creeks and …
