The Development Of A Modified Soil Shear Vane, Vernelle Truman Smith

Masters Theses

"The purpose of this investigation was to determine how the soil shear graph could be modified to measure more accurately values of shear strength of fine-grained, cohesive soils. Several modifications were tried, however, the one that gave the most satisfactory results consisted of a vane and base plate mechanism.

A red clay of high plasticity obtained from a local cave was tested in both the natural or undisturbed state and in the remolded state. The only variable was the moisture content. Compaction effort was the same for all remolded specimens. Tests were conducted on undisturbed samples taken with thin walled …

Checking Rigid-Framed Structures By Extended Moment-Area Equations, Lucky Li-Chi Chow

Masters Theses

"Using the known moments obtained from the moment distribution solution, the extended moment-area equations are used to check whether or not delta x, delta y, delta theta are truly zero, or are any other quantity they are supposed to be. In order to get a reasonably correct answer, a solution must meet both the elastic checks and the static checks for their equilibrium and compatibility functions. Using the extended moment-area equations, the magnitudes of the slopes and deflections at all of the joints in framed structures can be found easily"--Abstract, page ii.

An Investigation Of Consolidation On Compacted Partially Saturated Clarksville Soil, Ma-Tai Matthew Chen

Masters Theses

"The Terzaghi theory of consolidation and the assumption of his theory, pore pressure and effective stress, secondary compression and rheology were all reviewed and discussed. Eight compacted unsaturated samples made from Clarksville silty clay (CL) under different compaction efforts and moisture contents were subjected to consolidation load increments. Each load increment was maintained for 24 hours. An extra compacted sample was loaded for one month to investigate secondary compression.

From e-p curves, five settlement vs. compacted embankment height curves were derived for different compaction effort and moisture contents. These curves may be of practical use, when checked by field measurements …

Bending Of Isosceles Right Triangular Plates, Ping-Tung Huang

Masters Theses

"In this thesis the series expansion method is used to obtain the moments and deflections of an isosceles right triangular plate bent by arbitrary transverse loads. The method is based on using an antisymmetric load on a square plate. Two boundary conditions are solved and the numerical results obtained for these cases are tabulated"--Abstract, page ii.

A Numerical Solution For Beam-Columns On Non-Linear Foundations, Wendelin H. Mueller Iii

Masters Theses

"A program for Matlock's recursive method, a numerical method which will analyze beams and columns with linearly varying spring supports, was modified to enable the solution of such members supported by non-linear springs. This modification was accomplished by an iterative technique. The final result of this paper is a computer program which can be used to solve beams or columns with non-linear spring supports, giving as output the deflection, slope, moment, shear, net load and curvature of the structure at uniformly spaced locations"--Abstract, page ii.

A Numerical Method For The Solution Of Cylindrical Shell Structures, Chen-Jow Hsiao

Masters Theses

"Many studies and analyses of shell structures to date have been either so complex and laborious as to preclude their application in practical design problems or so approximate, because of basic assumptions, as to limit their scope of application. Hence, a method of shell analysis which is convenient to use, reasonable in its results and general in its application is really needed. It is the purpose of this study to supply such a method of analysis.

In this investigation it is proposed to replace the shell structure which has an infinite number of degrees of indeterminancy with an analogous framework …

The Effect Of Initial Moisture Content On The Swelling Characteristics Of Putnam Soil, William Howell Branum

Masters Theses

"The literature on swell and swell pressure in expansive soils was reviewed. The effect of initial moisture content on the swelling properties of untreated Putnam silt loam was investigated by performing free swell and swell pressure tests on specimens with varying initial moisture contents compacted to a constant dry density. The free swell tests were conducted by allowing the samples to swell freely under a low load (the weight of the plunger and the porous stone in the swelling apparatus) and measuring the volume change that resulted. The swell pressure tests were performed using two different procedures: (1) determining the …

Analysis Of Sand Asphalt Mixtures, Maurice A. Sayegh

Masters Theses

"The objective or this investigation was to determine the optimum percent of asphalt which should be added to the sand asphalt mixture. Also the effects of filler on the properties or the sand-asphalt mixture were evaluated.

The variables in this study were mineral filler, asphalt cement, and asphalt content. The sand used in this study was sub-rounded, and uniformly graded. The asphalt was asphalt cement with two different penetrations, one of 85-100 penetration grade and the other of 120-150 penetration grade.

Three different groups of mixtures of sand-asphalt were prepared. The first group consisted of adding 85-100 penetration asphalt to …

Numerical Solution Of Water Hammer Analysis Including Friction Losses, Lih Hsun Weng

Masters Theses

"The water hammer phenomena is a very important problem in pipe lines and gate operations. There are many analytical solutions tor water hammer problems including friction losses, but most of them use a linear approximation tor the friction effect that is different from the actual situation. Also the existing methods for solving water hammer problems involve difficult mathematical operations that are impractical and inaccurate.

In order to find a more rapid method for solving water hammer problems including friction losses and to obtain closer agreement with the actual condition, the problem is solved here using the basic partial differential equations …

Fluid Flow In Pipes Of Rectangular Cross Sections, Bruce Harold Bradford

Masters Theses

"Head loss due to fluid friction was measured in smooth conduits of rectangular cross section. The data covers the laminar and turbulent range. Results were compared with previous theoretical and empirical data.

The customary practice of calculating head loss in non-circular conduits by use of the friction factor obtained on an “equivalent” circular pipe was discussed. It was found that this practice is successful in square cross sections undergoing turbulent flow. In laminar flow, however, this method is not accurate"--Abstract, page ii.

A Procedure For Analysis Of Three-Segment Symmetrical Balcony Beams, Ronald A. Hansen

Masters Theses

"A procedure for analysis of three-segment symmetrical balcony beams unsymmetrically loaded was derived whereby the normally complicated energy solution is eliminated. A moment distribution technique is used in the solution of the first and second phases of the problem. Tables are given to aid in determining the proper distribution factors. Due to the complexity of the third phase, a table of solutions is given for varying values of length, geometry, etc.. An example problem is also given demonstrating the use of interpolation within the tables"--Abstract, page ii.

A Study Of Sedimentation In A Well Regulated Major Drainage Basin - The Monongehala, Allegheny And Upper Ohio Rivers, William S. Wood

Masters Theses

"This investigation is concerned with the study of various programs employed in reducing and controlling sediment. The measures employed by the U.S. Soil Conservation and Forestry Services to control and reduce erosion, the primary source of sediment, was studied. The flood control and river navigation structures constructed and operated by the U.S. Army Corps of Engineers and the effect of these structures on sedimentation was also evaluated. State and local community regulation and control of exploited natural resources was studied to determine their influence on the generation and control of sediment.
The Allegheny, Monongehala and upper Ohio River Drainage Basin …
