The Effect Of Epoxy Resins On The Durability And Unconfined Compressive Strength Of An A-1b Soil, Guy H. Payne Jan 1966

The Effect Of Epoxy Resins On The Durability And Unconfined Compressive Strength Of An A-1b Soil, Guy H. Payne

Masters Theses

"This thesis reports the procedure and results obtained from the stabilization of a clean poorly graded sand with various amounts of epoxy resin. The same soil was also stabilized with varying amounts of Portland cement in order to have a basis for comparison of the results obtained. The sand used in this research came from the Meramec River in Central Missouri and is classed as an A-lb soil by the AASHO classification system. The following tests were performed on the stabilized samples: 1. Specimens were molded and compacted at 4%, 6%, 8%, 10% and 12% portland cement by weight of …


Fluid Flow In Pipes Of Rectangular Cross Sections, Bruce Harold Bradford Jan 1966

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 Jan 1966

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.


The Effect Of Initial Moisture Content On The Swelling Characteristics Of Putnam Soil, William Howell Branum Jan 1966

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 …


A Study Of Sedimentation In A Well Regulated Major Drainage Basin - The Monongehala, Allegheny And Upper Ohio Rivers, William S. Wood Jan 1966

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 …

Numerical Solution Of Water Hammer Analysis Including Friction Losses, Lih Hsun Weng Jan 1966

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 …
