Analysis Of Flat Plates By Reaction Distribution Method, David D. W. Yang Jan 1962

Analysis Of Flat Plates By Reaction Distribution Method, David D. W. Yang

Masters Theses

"This study was made to analyze rectangular flat plates by the method of Reaction Distribution and to compare results obtained by this method with that of other methods. The basic approach is to divide the plate into an equivalent grid system and introduce temporary supports at the intersecting joints. The results from this study shows that the Reaction Distribution method is useful in a qualitative analysis of the behavior in a plate but is less satisfactory in obtaining reliable quantitative results"--Abstract, page 2.


A Study Of Composite Beams Made To Find An Approximate Relationship Between The Top And Bottom Flange Steel Ratio, Murli U. Hasrajani Jan 1962

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.


A Machine-Laid Surmountable Bituminous Concrete Median, Robert L. Florence Dec 1961

A Machine-Laid Surmountable Bituminous Concrete Median, Robert L. Florence

Kentucky Transportation Center Research Report

On August 28, 1961, personnel of the Research Division were requested to observe a demonstration of a newly developed Etnyre Median Paver. The demonstration was given at the Lehman-Roberts Company plant in Lexington, and was arranged primarily for the benefit of the paving contractor working on Euclid Avenue in Lexington. The paving contract called for the construction of a surmountable bituminous concrete median which, to our understanding, is the first instance for construction of that type to be machine-laid. Some doubts arose during the demonstration as to the ability of the machine to hold alignment and to give adequate compaction. …

An Investigation Of Indeterminate Structures Stressed Beyond The Proportional Limit, Jack B. Joyce Nov 1961

An Investigation Of Indeterminate Structures Stressed Beyond The Proportional Limit, Jack B. Joyce

Civil Engineering ETDs

In the structural field the methods of designing have been geared to the development of materials...In a more current appraisal we see steel and concrete being updated still further. Pre-stressed concrete is a common sight in present day construction work and, to a lesser extent, the educated eye sees rigid frames designed to ultimate load criteria. Here again are cases where materials are studied and found to possess characteristics that are adaptable to advance methods. The key to all such improvements is still the realization and utilization of material properties.

Water Requirements For Waterfowl Areas Near The Great Salt Lake Parts V-Vi, J. E. Christainsen, Ming Chang Tsai, D. K. Kaushik, J. B. Law, J. W. Teeter

Reports

This report reviews activities on this project since the Progress Report, Part IV, June 1961.

The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.

Most of the routine work on the project during the summer was done by …

Portland Cement Stabilization Of Western Kentucky Gravels, Robert C. Deen Nov 1961

Portland Cement Stabilization Of Western Kentucky Gravels, Robert C. Deen

Kentucky Transportation Center Research Report

It has been known for some time that some Western Kentucky bank gravels perform rather poorly as base or shoulder material. In the fall of 1956, the Division of Research participated in the experimental design and evaluation of a group of ten rural highway base stabilization projects. Two of these projects, one in Ballard County and one in Marshall County involved the stabilization of Western Kentucky bank gravels with a bituminous material; AE-200, a mixing-type emulsion, was used.

The performance of these bitumirlous-stabilized gravels has not been entirely satisfactory. Even though little tendency was noted for the asphalt to bleed …

New Genera And Species Of Myripristid Fishes, In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes) Oct 1961

New Genera And Species Of Myripristid Fishes, In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes)

School of Mines and Metallurgy Bulletins

Studies of fossil and Recent otoliths (sagittae) supply an important line of evidence, bearing on classification of teleost fishes, supplementary to that of anatomy, osteology, and "phylogenetic" paleoichthyology.

Squirrelfishes ( " Holocentridae" of authors) are generalized forms in which evolutionary divergence of some mag nitude is reflected in unpreservable details of anatomy, inconspicuous skeletal structures, and striking differentiation of the sagittae. Otoliths show the holocentroid complex to consist of one homogeneous unit (l\fyripristidae, elevated) and another more heterogeneous group (Holocentridae, restricted). These lineages have been separate. at least since the middle Eocene.

A revised classification, based on available lines of …
