A Study Of Composite Beams Made To Find An Approximate Relationship Between The Top And Bottom Flange Steel Ratio, Murli U. Hasrajani

Masters Theses

"At present in building construction the use of the composite beams is not very common. The use of the concrete beams is seen in almost all construction. By using composite beams in building construction more durability and savings in cost could be achieved. This paper shows an approximate design procedure which could be followed without running a number of trials with different sections to arrive at the required one. The ratio of top flange steel to the bottom flange steel can be determined if one knows the loads, span and the depth of the beam required"--Abstract, page i.

Effects Of Solids On Friction Factor In A Sand-Water Mixture, Frank J. Capek

Masters Theses

"At the present time various industries in both the United States and Europe are very interested in using pipelines as a means of transporting solids. The pumping of solids in pipelines isn't new, however, many of the pipelines in use today were constructed on an empirical basis. This is primarily due to the lack of knowledge concerning the flow properties in fluid-solid mixtures and slurries. With this need for fundamental information in mind, the author made a study on the effect solids have on the friction factor in fluid-solid mixtures.

In this paper various percentages of fine and coarse sand …

Investigation Of Vertical Internal Spillways, Paul R. Munger

Masters Theses

"This investigation resulted in the development of a means of predicting the discharge of water through an internal spillway type rockfill dam. From the data obtained during the various tests, equations were developed by which the coefficient of discharge for an internal spillway type rockfill dam can be determined when the core height, rock size and head causing flow are known. The equations give results with an error of less than 5%, which is adequate for engineering works"--Abstract, page 2.

The Effect Of The Ultraviolet Portion Of The Sun Spectrum On Chlorine Residuals In Water Supplies, Tumkur Mohmed Ameer Ahmed

Masters Theses

"The effect of sunlight on chlorine residuals in water supplies was investigated to provide original and basic information of value to the water purification field.

Three different water systems were employed: (a) The Simplified Water System, (b) The Ground Water System, and (c) The Surface Water System. The RS Sunlamp provided an appropriate source of ultraviolet radiation. A 10 mg/1 chlorine concentration was used. The pH values of 7 and 10 and the illumination intensities of 145 and 200 foot candles were employed. Iodometric determination of chlorine residuals was the main parameter used.

It was found that the chlorine residuals …

A Study Of The Hood Inlet And Its Possible Use As An Overflow Structure For A Sanitary Lagoon, Richard Irwin Boe

Masters Theses

"A closed conduit, such as an overflow pipe for a conservation pond or a sanitary lagoon, will not flow full if laid on a slope that is hydraulically steep unless the pipe entrance receives special attention. A steep conduit slope is necessary to insure that the pipe entrance controls flow.

The recently introduced hood inlet will permit the closed conduit to flow full, even if on a hydraulically steep slope, upon a slight submergence of the inlet crown. The hood inlet is formed by cutting the pipe at an angle so that the crown of the inlet projects beyond the …

The Effect Of Phosphoric Acid On Compaction And Shear Characteristics Of Pure Kaolin Clay, Bhupat Hargovinddas Mehta

Masters Theses

"The work presented is the investigation of the effect of phosphoric acid on the compaction and shear characteristics of pure kaolin. Pure Georgia kaolin clay average particle size of five microns was mixed with different percentages of phosphoric acid. These mixtures were permitted to react for varying periods of time. The results of the study indicate a notable and gradual increase in dry density of the kaolin with increasing percentages of phosphoric acid admixture. The acid admixture ranges from one up to nine percent of the dry weight of the clay. Increase in cohesion of the clay with increase of …

Effect Of Deflections For A Flat Plate By Slope-Deflection-Gyration Method, William Hsin-Loo Ying

Masters Theses

"Since the procedure for the theoretical solution of a rectangular flat plate or slab is complex, many approximate methods for determining the moments and deflections of such plate have recently been developed. One of these methods is the so called Slope-Deflection-Gyration Method which is performed by means of basically well-known structural theories - slope-deflection and torsion.

For a given plate, it is assumed that the plate is to be divided up into a grid of strips or equivalent beams at right angles to each other. The joints of this grid are assumed to be rigidly intersected and be permitted to …

Deformations And Bending Moments For A Building Slab With A Central Opening, Wu Ping-Yung

Masters Theses

"The adaptability of the classical slope-deflection method analysis to the analysis of uniformly loaded building slab is the subject of this study. The paper demonstrates the use of slope-deflection in computing deflections and bending moments in uniformly loaded square building slabs both with and without central square openings. The results obtained are compared with results of other methods found by other investigators.

Numerous methods have been proposed for use in solving plate or slab problems. The exact solution in the form of a fourth order partial differential equation has proved to be of value in relatively few cases where boundary …

Effect Of Lime & Cement Additives On The Dynamic Modulus Of Elasticity Of A Clay Soil, Ismail Yolar

Masters Theses

"This thesis is a study to determine the values and characteristics of modulus of elasticity and the modulus of rupture of a clay soil stabilized with lime and cement in an effort to pave the way for including these values in design criteria.

The modulus of elasticity and the Poisson's ratio were obtained by sonic method. Specimens were broken in flexure for modulus of rupture. Experiments were performed with; (1) untreated soil, (2) soil with 4, 6, and 12 percent cement additive, (3) soil with a 3 percent lime additive and 0, 4, 6, and 12 percent cement additive, (4) …

A Study Of The Energy Dissipation And The Related Pressures And Velocities Of Cylindrical Tank Type Stilling Basin, Graham Wayne Wood

Masters Theses

"In all hydraulic structures that hold back water, whether for the purpose of power, irrigation or flood control, all must have some means of dissipating the energy that is produced by the movement of the water from the pond or reservoir to the tailrace. The method of dissipation depends largely on downstream conditions, terrain and economics. The dissipator is to prevent scour and the undermining of the dam itself. The construction of any type dissipator should be the best one available for the least cost of construction. However, space limitations may dictate another type of dissipator. It has been recommended …

Use Of Light-Weight Steel Strapping As External Reinforcing To Concrete Beams, John O. Buchanan

Masters Theses

"As a result of some recent failures in reinforced concrete construction throughout the United States, a study was made by several national authorities to find some remedial measures of strengthening existing structures without rebuilding. A system was developed, using high strength steel bands applied externally to beams, to act as stirrups, which has been highly successful. It not only greatly increased the strength of beams already in place but was used to repair members which had already failed.

The application of these bands was made under very exact specifications, using closely controlled procedures, with many physical refinements, in order to …
