Waterfront Construction In New York Harbor, Carman William Garrison

Theses

The following chapters are devoted to the various phases of that branch of construction which is followed from the offshore side of the waterfront. This branch, in the parlance of the building trades, is known as dockbuilding. Years ago all waterfront structures in New York Harbor were constructed almost entirely of timber and experience taught that the most economical approach for building docks and wharves was made by utilizing floating piledrivers and derricks. Thus it happened that dockbuilders became skilled both in the use of wood framing tools and in handling marine equipment. Modern dockbuilders must have, in addition to …

Recommended Procedure For The Computation Of Rights Of Way, Leon Hershkowitz

Professional Degree Theses

"This thesis sets forth a recommended procedure for the computation of areas included in "rights of way," using the principle of double meridian distances.

For a considerable number of years, it has been the opinion of the author that steps should be taken to arrive at some form of standardization in the procedures necessary in the computation of areas involving right of way and to more or less standardize legal descriptions pertaining thereto.

One need only examine the records of the various County Recorders in one particular state or in different states and he would be entirely convinced that such …

Research Investigation Of Seepage Control For Dams And Levees, Robert Raymond Brookshire

Professional Degree Theses

"The problems of a century old levee system have provided excellent research for the Corp of Engineers and others in the design and construction of earth dams for flood control, navigation and multi-purpose projects. A special problem on which valuable knowledge has been gained is that of seepage control. The experiences obtained in recent years have been supplemented by theoretical developments in the field of soil mechanics, but it is believed that considerable information will be gained on seepage control from further investigation and experience.

The safety factor to prevent failure from seepage is believed to be the most critical …

Design Of A Wind Tunnel For The Missouri School Of Mines And Metallurgy, William E. Speece

Masters Theses

"For some time there has been a need for a wind tunnel at the School of Mines for experimental work in the Civil and Mechanical Engineering Departments. With the expanding program and the possibility of establishing an Aeronautical Engineering School here, the need will be even more pronounced. So the problem will be of definite practical value. It was the original idea to design a small tunnel, build the tunnel, and to run a series of smoke tests on various structural models. However, after discussing the possibility of such a problem with school authorities, it was decided that if a …

Efficiency Of Various Types Of Reinforcement In Controlling Opening Of Cracks In Concrete Pavements, Frederick Richard Heartz

Masters Theses

"To date very little work has been done on the subject of the amount of crack opening for different loads on concrete pavement. It is a known fact that these cracks must be held together sufficiently to have aggregate interlocking action if the pavement is to transfer loads from one edge of a crack to the other. The maximum permissable [sic] opening has been set at .027 inches by the Highway Research Board. The author has attempted in this investigations (1) to determine the effect of different spacing and different sizes of longitudinal and transverse wires in controlling crack opening …

The Establishment And Analysis Of A Triangulation System For The Teaching Of Advanced Surveying, Philip Blaine Newlin

Masters Theses

"The first thought of establishing a triangulation system for the University of Arizona student work was conceived early in the fall of 1947, when the author first learned that he would be in charge of the advanced surveying field parties during the spring semester. These men were to be instructed in the accepted manner of conducting surveys of higher order. This would include the measuring of a base line of second or first order accuracy, the turning of horizontal angles with this same degree of accuracy, the determination of the azimuth of the lines by astronomical observations, the running of …

Interrelationship Of Transverse Anchorage And Adhesive Bond In Welded Wire Reinforcement, Alan Arthur Becker

Masters Theses

"...Welded Wire Reinforcement Fabric has been applied only to certain "light types" of reinforced concrete construction. It has not as yet been applied as main tension reinforcement for most concrete structures, mainly due to the fact that a thorough investigation of the potentialities and possibilities of welded wire fabric has not as yet been conducted. It is expected that the data collected in this investigation coupled with data collected in similar investigations performed at the Missouri School of Mines and Metallurgy will furnish the basis for a structural and economic comparison between welded wire fabric and ordinary reinforcing bars. The …

Aerodynamic Research For An Improved Rotor Control System On Helicopters, Delmar Wallace Breuer

Masters Theses

"Since the author has always been interested in Aeronautical Engineering, and in particular, rotary-winged-aircraft, the problem of research for aerodynamic improvement of rotary-wing control systems was chosen. This problem was suggested by the Army Aircorps Officials of Wright-Patterson Field of Dayton, Ohio as being a valuable and practical problem for the government. It is also valuable and practical for the author since it follows his general course of undergraduate study and since it fits closely into the field for which he is preparing himself...The requirement with which the author is most concerned is the design system for the producing of …

A Correlation Of Formulas For The Flow Of Fluids In Pipes, John Gorman Duba

Masters Theses

"At present there exist two quite distinct fields in fluid flow in pipes, the one in water supply and the other in the petroleum industry. It is the purpose of this paper to discuss the various pipeline flow formulas as used in both fields and to correlate the exponential type formula which is much used in practice with the Nikuradse curves obtained in the laboratory"--A Brief Historical Review, page 5.

The Theory Of Limit Design As Applied To The Design Of A Continuous Beam Over Three Supports, Robert F. Davidson

Masters Theses

"The theory of Limit Design is the application of the theory of Plasticity to the estimation of the actual carrying capacity of a structure. In this theory, as it is applied to statistically indeterminate structures, the areas of most unfavorable stress are allowed to be stressed beyond the yield point and into the plastic range of stress. It was formerly held that, by assuming elastic behavior, all questions of strength of materials that concern the Structural Engineer were capable of solution. However, it is now becoming recognized, from actual measurements of deformations of structures and from tests carried to near …

A Study Rigid-Frame Design Versus Truss-And-Column Design, Stephen H. Goodman

University of the Pacific Theses and Dissertations

This paper describes the investigation of a mill building bent of truss and column design, a redesign using a rigid-frame, and an estimated cost of each design. For sake of brevity the overall design of the building (sway bracing, lateral bracing, purlins, girts, roofing, siding, and bay spacing) was assumed to be the same for both designs. It is possible that this assumption cannot be made and the estimates of cost, therefore, are in error. In actual practice the complete redesign of the building should be considered.

Standardization Of No-Passing Zone Pavement Markings, Glen Nickolas Hackmann

Professional Degree Theses

"This thesis is a comprehensive treatment of present methods practiced by the various Highway Departments in the United States. It presents in particular current methods used by the State Highway Departments and the Public Roads Administration in marking no-passing zones throughout the country. For a long time it has seemed to the author that such a study was needed by both students and highway engineers. Road-design information of great value has developed over the years and often has been published but never assembled in a single orderly presentation stripped of excessive overlapping"--Preface, page ii.

The Mechanical Anchorage Value Of The Transverse Wires In Welded Wire Reinforcement Fabric, Ernst August Weinel

Masters Theses

"The tests reported in this paper were performed in an effort to secure data concerning characteristic properties of Welded Wire Reinforcement Fabric. This fabric has been used, up to the present time, primarily for temperature reinforcement. Limited attention has been focused on its potentialities for use as main tension reinforcing steel, particularly concrete highway slabs and floor slab reinforcement for buildings. The manufacturers of the Welded Wire Reinforcement Fabric believe their product can be used to better advantage as main tension reinforcement in reinforced concrete structures both from an economic and structural viewpoint, than structural steel reinforcing bars"--Object of Research, …

Improving Railroad "Less-Than-Car-Load" Freight By The Use Of Containers And Container Cars, Kenneth Walter Schoeneberg

Masters Theses

"Less-than-car-load (L.C.L.) freight has been and is becoming more of an acute problem with the railroads of this country. They are rapidly losing this vital and important function of their transportation service. Following, is a brief history of the railroads along with a discussion of their present day problems dealing with less-than-car-load freight service. It is believed, by the author, that a system of developing and using containers and container cars along with a pick up and delivery service will solve these problems the railroads now experience. If this method of freight transport would be adopted by the railroads, not …

Stresses In A Plate Having A Relatively Small Circular Hole And Loaded Parallel To The Axis Of The Hole Under Various Conditions Of Constraint With An Application To Deep Oil Wells, A. Dale Topping

Masters Theses

"The object of this investigation is to determine the stresses about a hole in a thick plate of large dimensions compared with the radius of the hole when the plate is loaded parallel to the axis of the hole under various conditions of restraint, and to apply the results to the case of a deep well. The case of a plate with an initial stress in its plane is also considered...The problem arose from difficulties encountered in the drilling of deep oil wells. After drilling has proceeded to a certain depth, the sides of the bore hole apparently collapse and …

A Comparison Of The Use Of Polaroid And Colored Filters In The Multiplex Aeroprojector, Robert Greig Livingston

Masters Theses

"The purpose of this thesis is the drawing of a comparison between the use of the colored filters, which are normally employed in the multiplex aeroprojector by various mapping agencies throughout the country, and the use therein of Polaroid filters. The filters in the aeroprojector serve to break the projection of a stereoscopic pair of photographs into two impressions which are viewed separately by each eye of the observer, thus providing the main requirement for the observance of a three-dimensional effect. this stereoscopic effect is utilized in the multiplex plotting machine for the delineation of contours...In order to form a …

Floods Of May 1943 In Missouri, John August Short

Professional Degree Theses

"The year 1943 will be remembered for a long time as a year of great floods in the Middle West. Floods were occurring in some section of Missouri from April to June. The period of highest stream flow in general occurred during the month of May, and it is the May flood to which this paper pertains. It is quite possible that the importance of this flood is not generally recognized. Although everyone realizes that it was a major catastrophe, only planners for the future, particularly designing engineers, can fully appreciate the benefits which will be obtained from the information …

A Study Of The Pollution Of The Meramec River, William Quentin Kehr

Professional Degree Theses

"Early in 1940 a project was undertaken for a complete survey of the Meramec River Basin. This project, of which the pollution study was a part, was one of the most extensive surveys made of an entire river basin and included detailed studies of soil erosion, land, use, pollution, rainfall, and recreation in the Meramec Basin. The pollution study covered that portion of the Meramec River from its confluence with the Mississippi River to Steelville, a distance of about 140 river miles; the Big River from its mouth to a point west of Flat River, a distance of 107 river …

Research Investigation Of Organized Drainage Districts In Mississippi, Lee Dorsett Dumm

Professional Degree Theses

"In the early days farmers attempted to drain their land individually, but they soon found that water did not recognize property lines. One farmer would ditch his land only to find that the water from his neighbor's farm would wash over has land and fill up his ditches. Another would attempt to ditch his land, but would find that no outlet was available for his ditch unless he constructed it across the land of his neighbor. Because of such situations, groups of farmers cooperated in constructing drainage improvements. However, difficulty was encountered in reaching an agreement as to the division …

Photoelastic Investigation Of Short Beams, Ross R. Carrolla

Masters Theses

"In this investigation the author used beams made of Bakelite. They were of rectangular cross-section and centrally loaded. These beams were viewed in polarized light and the maximum fiber stresses observed in that manner were compared with those computed from the flexure formula. The purpose was to determine the minimum length-depth ratio for which the latter gave fairly accurate results"--Preface, page 6.

Malaria Control Engineering On The Pickwick Reservoir, Cornelius Wolfram Kruse

Professional Degree Theses

"During the past year in an area extending south of a line between Norfolk, Virginia and St. Louis, Missouri, it has been estimated that about 10,000 deaths and staggering economic losses were caused by malaria fever...Since the recent inauguration of river development projects on the various streams in the so-called "malaria belt" of our country, malaria control methods on impounded waters have been of increasing concern to the health workers of the South...Mosquito control on impounded waters must be constructed into the dam design and requires a careful program of reservoir preparation or conditioning of the body of water so …

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 …
