A method of seismic design for prestressed concrete highway bridge girders

Creator:: Lam, Kwok To
Abstract:: 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...

Economic comparisons of different highway networks in a given region

Creator:: Ergün, Tevfik
Abstract:: 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...

A study of the coagulation of kraft effluent by sea water

Creator:: Andrews, Ben Neal
Abstract:: 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...

Design criteria for waste water lagoons in Oregon

Creator:: Putnicki, George John
Abstract:: 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...

Dynamic analysis of three-dimensional frames

Creator:: Scholl, Roger Edwin
Abstract:: 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...

The effect of mixing on the oxygen uptake rate of estuarine bottom deposits

Creator:: Martin, Duane Collins
Abstract:: 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....

Matrix analysis of structures with semi-rigid connection

Creator:: Grant, Joseph Edward
Abstract:: 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...
