The effects of vertical ground motion are particularly significant
in the design of highway bridge girders. Conventional codes do
not recommend methods for solving the problem. The intent of this
work is to suggest an approach for such design.
A set of curves for velocity spectra which are the average...
This thesis presents an economic comparison of three different
highway networks which serve an area of 64 miles by 83 miles in size.
Each network is designed to carry the same traffic between any two
towns but is different in total length.
Costs of right of way, excavation, pavement and...
The coagulation of effluent from the kraft pulping and
papermaking process was investigated. The amount of material
coagulated from saline mixtures of the effluent is determined
as a function of time, salinity, kraft effluent
concentration, and mixture pH. Individual sources of salinity
include sea water and several different solutions of...
Waste water lagoons have been used as a satisfactory means of
treating domestic and certain industrial wastes in many parts of the
country. Many of the parameters that govern the applicability of this
type of treatment process are climatic in nature, and critical evaluation
of local climatic conditions, as well...
The response of three-dimensional frames subjected to an arbitrary
dynamic force is studied. The method of mode superposition
is used to obtain the frame response solution. Two different modeling
systems are used to idealize the frame. These are the "discrete
mass system" and the "continuous mass system." For an example...
A study of the effect of mixing on the oxygen uptake rate of
estuarine bottom deposits is presented. The method of study involved
the mixing of samples of bottom deposits with the overlying water to
result in concentrations of suspended matter in the same order as
observed in the estuary....
This thesis presents a matrix analysis of structures
with semirigid connections. The stiffness factor of a
connection has been assumed to be a constant as represented
by the initial relationship of moment versus
rotation. Three cases are considered: Case I - structures
with semirigid connections, column width and beam
depth...
