Design Study Of A Three Span Continuous Tied-Arch Bridge, George Perry Steen Jan 1939

Design Study Of A Three Span Continuous Tied-Arch Bridge, George Perry Steen

Masters Theses

"In this study of the continuous tied-arch bridge, having one main span and two equal side-spans, the following items are endeavored: (1) To set up the total internal work equations and to find the values of the unknown forces or redundants. (2) To compute to maximum moments for design and to complete the design of the super-structure for one bridge. Details, such as the gusset plates, rivets, connection angles, etc., are not designed; the effect of such being allowed in the design for dead load as a certain per cent for details. (3) To set up hypothetical conditions for other …


Investigations Of Diversion On The Lower Mississippi River, Elmer John Sperling Jan 1932

Investigations Of Diversion On The Lower Mississippi River, Elmer John Sperling

Masters Theses

"The purposes of this investigation were severally as follows: (a) To determine the feasibility of digging pilot channels to scour out channels through the Beouf and Atchafalaya basins of sufficient size to handle the project flows contemplated for these basins in time of superflood. (b) To determine the best forms of the pilot channels and the best approximate dimensions. (c) To determine velocities conducive to erosion, transportation, and deposition; the manner and rate of enlargement under below-bank, bankful, and overbank flows; and the character of trace to be expected after enlargement of the proposed channels. (d) To investigate any suggested …


A Study Of Influence Line Analysis Of Stresses In A Cantilever Steel Highway Bridge, Lawrence King Snyder Jan 1932

A Study Of Influence Line Analysis Of Stresses In A Cantilever Steel Highway Bridge, Lawrence King Snyder

Masters Theses

"As its name implies, this thesis introduces to the reader the basic conceptions and principles of the use of influence line analysis of the structural theory relating to calculation of stresses in a steel cantilever bridge truss"--Preface, page i.


Lactose Fermenting Bacteria In The Water Supplies Of The Rolla Quadrangle, Joe Beaty Butler Jan 1924

Lactose Fermenting Bacteria In The Water Supplies Of The Rolla Quadrangle, Joe Beaty Butler

Masters Theses

"I. Preliminary investigations. This includes the securing of 139 water samples from water sources in the Rolla Quadrangle, and inoculating 1cc samples from these into Dunham's Lactose tubes and thereby getting lactose gas production checks on the field samples. II. Confirmatory tests. This consisted in the isolation of lactose fermenters on Eosin-Methylene Blue Agar and checking of the cultures back through the lactose and then through dulcitel and saccharose so as to complete Jackson's Classification. 106 cultures were classified in this manner. III. Running through a complete set of tests of pure cultures, so as to completely (as possible) identify …
