The Plastic Design Of Steel Cofferdam, Robert O. Disque

Theses

The fundamental purpose of this thesis is to employ the plastic theory in the design of a hypothetical steel sheet pile cofferdarm. Prior to undertaking this work, the author had had no previous experience with the plastic theory. Therefore, a portion of this thesis is devoted to the development of the fundamentals necessary for the actual design computations.

The theory of plastic analysis has been used as far back as the 1920's in Hungary for the structural design of apartment buildings. It is, however, only in recent years that the theory has been utilized to a significant degree in this …

The Effects Of Fly-Ash On Dynamic Modulus Of Elasticity Of A Concrete Mortar, Bill L. Atchley

Masters Theses

"Over the last few years an increasing amount of interest has been shown in the use of prestressed concrete. As is true in many new methods of design or construction, the properties of existing materials to be used sometimes fail to meet all the desirable characteristics, and certain modifications might be advantageous. This is certainly true of prestressed concrete design and construction, in which a lower modulus of elasticity accompanied by a minimum loss in strength would be desirable. If a lower modulus of elasticity could be obtained for concrete, a lower prestressing load could be used and still maintain …

Design Of Vierendeel Trusses, Richard Denis Pearson

Masters Theses

"The Vierendeel Truss, or Rigid Frame Truss, was first introduced by Professor Arthur Vierendeel in Belgium at the beginning of the century. The Vierendeel Truss differs from the more common triangulated truss in that it contains no diagonal members. The members of the truss are joined rigidly together and each member is required to transmit bending, shear and direct stress.

Professor Vierendeel claimed that Vierendeel Trusses are 20 to 30 percent cheaper than the conventional type of truss. This statement has been challenged by many who believe that this type of truss is fundamentally inferior to the more conventional type. …

Field Application Of The Membrane Filter Method For Bacteriological Quality Determination Of Water, Charles Liston Gambill

Masters Theses

"The purpose of this thesis is to demonstrate the definite advantages to be realized when using the membrane filter method as an accepted procedure for the bacteriological analysis of a water; and specifically when used under emergency or field conditions such as military units in the field. These same advantages would apply to Civil Defense and other such agencies when operating under emergency or field conditions.

Data from actual tests showing techniques, equipment and procedures used and augmented by other data available from research papers will be utilized"--Introduction, page 2.

Design Of Plain Concrete Runways And Taxiways Of A Class 4 Airport, Erkmen Erkmen

Masters Theses

"This thesis is a study for determining the most economical design for the pavements of Adana Airport. It is a study of redesigning efficient and safe runways and necessary taxiways for a future service life of thirty years.

Adana is Turkey’s 6th largest city. It is a growing city. An airport in Adana also serves tor industrial purposes, serves for transcontinental airway systems. In Adana there is an important Nato Base and in a future war such an airport can be used for military purposes. For these reasons, it was decided to construct a class 4 airport* for the city. …

Stabilization Of Swelling Clay Soil By Additions Of Calcium Hydroxide And Calcium Oxide, Anthony Diler

Masters Theses

"As a study of all types of stabilization would be very lengthy, it was decided to make the object of this research the determination of the effect of the addition of different percentages of calcium oxide (CaO) and calcium hydroxide Ca(OH)₂ on the physical characteristics of a silty swelling sodium montmorillionite clay. The purpose of this addition is to flocculate the clay by utilizing a base exchange between the sodium and calcium ions, and thus change the physical characteristics of the soil. The soil by itself has the characteristics of a fat clay, that is it can be broken …

Application Of The Hveem Stabilometer To The Testing Of Open-Graded Bituminous Mixtures, R. A. Hannan

JTRP Technical Reports

This laboratory investigation was conducted with the purposeof determining the applicability of the Hveem Stabilometer to the testing of open-graded bituminous mixtures.

The study was divided into two major sections. The first of these investigated the validity of the Stabilometer displacement measurement when applied to open-graded specimens having large surface air voids. The second portion of the study had two specific purposes: (l) to investigate the stress-strain characteristics of open-graded mixturestested in the Hveem Stabilometer and (2) to determine whether surface voids on the ends of Stabilometer test specimens influenced Hveem stability values.

To check the validity of the displacement …

Structural Analysis By Minimum Strain Energy Methods, John B. Heagler

Professional Degree Theses

"Analysis of structure has its conception for the engineer early in his formal education and follows a set sequency from solving for equilibrium in simple beams and free bodies to more complicated solutions for stresses and deflections in multiply redundant structures.

Difficulty arises for the engineer when he loses the sequence of the subject and finds himself memorizing formulas and methods of solution without a clear and concise understanding of the underlying fundamental principles involved in arriving at these formulae and methods of solution.

The Aircraft Structural Analyst finds himself in a relatively new field of engineering structural design. Here …

Effect Of Hydrated Lime And Portland Cement On The Physical Properties Of Clay Soil For Highway Base Construction, Judson Leong

Masters Theses

"The intent of this research is to determine the change in physical properties of a clay soil caused by the addition of 2, 4, 6, 8 and 10 percent of hydrated lime and portland cement. The effects of these admixtures on the physical properties of the soil were observed by comparing the results of various laboratory tests. The properties chosen for comparison were: (1) liquid limit, plastic limit and plasticity index; (2) shrinkage limit and shrinkage ratio; (3) density and optimum moisture; (4) resistance to penetration; (5) compressive strength and (6) cohesion and angle of internal friction. In order to …

Effect Of Concrete Shrinkage On Stresses In Reinforcing Steel, C. Raymond Nowacki

Masters Theses

"Shrinkage is one of four phenomena that are considered as causing volume changes in concrete, the other three being creep, temperature change effects, and possible chemical disintegration. While all four are interrelated, the volume change due to loss of moisture is associated with the term shrinkage. Creep is the time-dependent change in volume resulting from external loads. A rise or fall of temperature will produce an expansion or contraction of concrete but also will affect the rate of shrinkage by increasing or decreasing the rate of moisture evaporation from the surface of the concrete.

In the design of concrete structures, …
