Masters Theses

"Studies of the effect of grinding on clay soils are summarized. Fundamental aspects of thixotropic phenomena are also explored. Vetters clay and Lebanon silt loam are used as test soils. these soils are ground to varying degrees and the deviations in physical properties are determined. Atterberg Limits, specific gravity, grain size, X-ray diffraction, and D.T.A. tests are run on each soil batch (ground for 0 minutes, 30 minutes, 60 minutes, and 120 minutes). A thixotropic study, consisting of unconfined compression and laboratory vane shear tests, of each soil batch is made. The results of the tests are analyzed, compared, and …

The Compressibility Of Preconsolidated Till, William H. Koechlein

Masters Theses

"Preconsolidated glacial till was tested "in-situ" with the Geoprobe and in the laboratory on undisturbed soil samples. The two soil testing methods were compared and three tests; consolidation, "thin-cake", and Geoprobe were analyzed to see if a more rapid method for determining the preconsolidation stress of soil could be developed. When comparing Geoprobe results to laboratory results for foundation conditions, it was found the two methods agreed on bearing capacity but differed significantly on settlement. The three tests analyzed for determining the preconsolidation stress indicated they are a function of preconsolidation stress even though there was variation in the test …

The studies were conducted on settled domestic sewage in three bench-scale continuous flow activated sludge units supplemented with jar tests. Major parameters employed included influent and effluent total phosphorus and chemical oxygen demand (COD), mixed …

The Influence Of Silt On The Compressibility Of An Illitic Clay, James Inman Spencer

Masters Theses

"This study was undertaken to investigate the effect of varying amounts of clay (illite) on the compressibility of a silt as it may be found in nature in a normally consolidated deposition. Laboratory procedure was designed to minimize sample disturbance so as to obtain, as nearly as possible, a virgin consolidation curve. By varying the amounts of silt and clay in a given sample, and sedimenting the sample from a soil-water suspension, consolidation test analyses were used for a comparison of the various samples. Results revealed that between sample mixtures of 40 and 60 percent silt there was a relatively …

A Comparison Of Proportional And Nonproportional Damping In Multistory Shear Buildings, Edwin C. Bailey

Masters Theses

"The purpose of this study was to determine whether proportional damping could be used to satisfactorily simulate the more practical nonproportional damping condition in multistory shear buildings. To accomplish this one computer program was written to analyze proportionally damped systems and another to analyze nonproportionally damped systems, each giving as output the frequencies, mode shapes, displacements, shears and moments and the maximum shears and moments. Shear buildings of two, three and four stories were studied in which the damping coefficients were varied from one to ten percent of critical damping. Although the programs could handle various other types, only linearly …

Thixotropic Effects In A Clay-Water System, John Arthur Mathes

Masters Theses

"Fundamental aspects of thixotropic phenomena are described, and previous investigations of thixotropic behavior in soil systems are summarized. The complex nature of the thixotropic phenomena as well as its general occurrence in fine grained soils is described. As existing hypothesis for thixotropic behavior based on initial non-equilibrium conditions is examined. Experimental results, as determined from a testing program on the Putnam clay, verify this hypothesis. The rate and magnitude of thixotropic strength increases of the Putnam clay were determined. Shear strength determinations were made by the unconfined compression and laboratory vane shear tests. The results of the tests were compared …

Shear Strength Behavior In Silts And Clay Mixtures, Alan T. Jackson

Masters Theses

"A series of consolidated undrained triaxial tests with pore pressure measurements were performed on laboratory sedimented samples having various known silt to clay content ratios. The clay used was commercial grundite clay from Goose Lake, Illinois, and the silt used was extracted from Lebanon Silt Loam from Rolla, Missouri. Silt was mixed with clay in the following percentages by weight: 0%, 20%, 40%, 50%, and 80%. Results indicate an increasing angle of internal friction with an increase in silt content. The unconfined compressive strength of the samples remained constant, as would be expected in a clay, with increasing silt content …

A Computer Adaption Of Plastic Analysis For Rigid Frames, Gerald Duane Galloway

Masters Theses

"A computer program for the plastic analysis of rigid frames is presented. The program is based on the virtual work method of plastic analysis. The great number of failure mechanisms that must be considered in any virtual work analysis are given in Appendix C. The use of the program as a design aid is also discussed.

Case History Of A Test Pile Program For The Redevelopment Of Newark Airport, Patrick De Michele

Theses

A pile load test program was conducted at Newark Airport to determine the most economical piles to be utilized to support the structure in the Redevelopment of Newark Airport. The controlling criteria were the pre-determined design capacity of 50 to 100 tons for the piles and conformance to the Newark Building Code regarding the maximum allowable loads on the Airport's bearing strata and the allowable settlements for test loaded piles. Thirty-four piles, ten timber, four steel H-piles, four pre-stressed concrete, seven cobi shell and nine steel pipe piles, were driven to determine driving characteristics of the piles and the reaction …

Application Of Multivariate Analysis In Predicting Water Yields In Utah, Leei-Luoh Wang

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The basic hydrologic data required to determine the water yield are usually unavailable for small basins and streams while increasing emphasis is being placed on their development. Therefore, some methods and techniques for estimating the amount of water available for development of these small units is needed .

The purpose of this study is to use the concepts and techniques of statistical analysis to develop equations which are useful in estimating the water yield of watersheds for which no stream flow records are available . The approach is an extension of earlier studies at Utah State University (1, lQ) in …

A Study Of The Compressibility Of Silty Soils., Marvin L. Byington

Masters Theses

"This study has been conducted to determine the applicability of the Terzaghi Theory of Consolidation and to determine the compressibility of silt soils with varying clay content. A pure silt was extracted from the Lebanon Silt Loam and mixed with varying amounts of the Onyx Cave Illite-Chlorite Clay. The compressibility of these mixtures was determined and an attempt made to apply the Terzaghi Theory in the analysis. It was found that the compressibility of soils high in silt content is very low. It was also found that the Terzaghi Theory may be applied to mixtures of 15 percent or more …

Effects Of Mixing Procedure Upon Uniformity Of Fibre Reinforced Concrete, Donald E. Nortrup

Masters Theses

"This thesis describes the effects of several methods of introducing wire fibres into a concrete mix upon the uniformity of wire fibre reinforced concrete. Various mechanical and manual methods of introducing the fibres were used and comparisons of the methods were based upon variability in splitting tensile strength and the quantitative distribution of the fibres as determined by visual inspection of sawed cylinders. Test results show that the tensile strength of concrete is increased appreciably by the inclusion of steel wire fibres in the mix and the uniformity of strength is similar to that of unreinforced concrete. The methods of …

The Measurement Of Explosively Induced Stresses In Rock-Like Materials With A Capacitive Transducer, Vincent Paul Crane

Masters Theses

"A capacitive transducer was developed for measuring the free surface motion in Hydrostone blocks loaded by an explosive plane wave generator approximately one foot from the specimen. The charge to specimen distance was adjusted to produce a single spall, the position of the fracture being noted on the recovered specimen. The longitudinal wave velocity in each specimen was determined by the ultrasonic pulse technique before each shot. From the above measurements the stress, strain and strain rate at the point of fracture were determined. An attempt was made to determine the actual fracture time with imbedded [sic] conductive graphite rods, …
