Quantification Of Pollutants In Surface Runoff From Agricultural Lands In Brookings County, South Dakota, Leland Lester Harms

Electronic Theses and Dissertations

Surface runoff from snowmelt and rainfall was measured 1n eastern South Dakota from seven sites (7.18 to 18.69 acres) during 1971 and 1972. All sites had single crops which included corn, oats, pasture and hayland. All land was farmed under normal farming conditions. Samples were taken periodically throughout each runoff event, and a single composite sample was made from the individual samples for a particular site. The composite sample represented the entire runoff event. The amount of rainfall and the runoff flow were measured. Determinations on the composite sample included total coliform, fecal coliform, fecal streptococcus, soluble pesticides, specific conductance, …

Analysis Of Continuous Curvilinear Structures By Infinite Matrix Series Methods, Trinh-Ngoc Rang

Doctoral Dissertations

"The objective of this dissertation is to present two methods of structural analysis for continuous curvilinear frames by using infinite matrix series as an extension of the well-known moment-distribution method. The sum of all unbalanced moments and thrusts relaxed at joints of a continuous system can be expressed in a compact and exact mathematical expression, which is in terms of the sum of a convergent infinite matrix series. With these unbalanced forces at joints, the final support forces may be calculated in a single stage of distribution and carry-over. The convergence of the balancing process is also demonstrated. Approximate results …

Nonlinear Optimum Design Of Dynamic Damped Structures, Mark E. Botkin

Doctoral Dissertations

"A method to optimize the weight of plane frames subjected to dynamic loads is presented. Restrictions are imposed upon the maximum dynamic stresses and displacements, desirable section moduli of the constituent members, and the range of values allowed for natural frequencies. Various considerations for rigid frame design include damping, the P-Δ effect, static girder loads, static column loads and girder shears transferred to the columns. A finite difference approach is presented to evaluate the shock spectrum which is used in conjunction with modal superposition to obtain the peak upperbound dynamic displacements and stresses for multistory and multibay frames. The displacement …

Dynamic Instability And Ultimate Capacity Of Inelastic Systems Parametrically Excited By Earthquakes, Wu-Hsiung Tseng

Doctoral Dissertations

"A procedure of analysis is presented for determining the dynamic instability and response of framed structures subjected to pulsating axial loads, time-dependent lateral forces, or foundation movements. Included in the analytical work are the instability criterion of a structural system, the finite element technique of structural matrix formulation, and the computer solution methods.

The dynamic instability is defined by a region in relation to transverse natural frequency, longitudinal forcing frequency and the magnitude of axial dynamic force. The axial pulsating load is expressed in terms of static buckling load for ensuring that the applied load is not greater than the …

The Des Moines Rapids: A History Of Its Adverse Effects On Mississippi River Traffic And Its Use As A Source Of Water Power To 1860, Donald L. Enders

Theses and Dissertations

During the 19th Century, the Mississippi River was the chief commercial highway in the United States. But for two impediments, the Upper and Lower (Des Moines) Rapids, its entire course of 2400 miles would have offered an untroubled thoroughfare to watercraft.

The federal government, as well as private concerns, attempted throughout the better part of that century to alleviate the river of its barriers and to develop its rapids as a source of power. Those attempts were disappointingly unsuccessful, however, and not until the advent of the 20th Century, when the nation had matured both economically and technologically, was the …

A Geographic Study Of Stone Houses In Selected Utah Communities, Barry M. Roth

Theses and Dissertations

This thesis will investigate the spatial location of stone houses and the areal differentiation of several characteristics of stone houses in selected communities. Some differences in cultural and historical factors and in types of building stone, quarries and quarrying techniques will be studied. The thesis will also investigate why stone houses are still in existence and things that owners, residents, and others like and dislike about them.

The Dynamic Response Of Continuous Beams And Plates, Robert L. Dineen

Civil Engineering ETDs

The objective of this investigation is to determine the complete response of undamped structural systems to time-dependent loads. Two systems, continuous beams and plates with equally spaced interior supports, are examined. Both have distributed mass and experience small linearly elastic deflections. The problems are formulated using the discrete mechanics method in which the response of a typical element of the system is first determined. A difference equation for the moments at the support locations is then derived by satisfying the force and compatibility conditions between adjacent elements. Finally, a closed form solution of this equation is obtained in terms of …

The Safety Barrier Dilemma, James H. Havens, Don L. Cornette, William M. Seymour

Kentucky Transportation Center Research Report

"Ran-off-the-road" fatal accidents currently account for approximately 65 percent of all freeway fatalities (1). Accordingly, ever-increasing emphasis has been given to the development of effective safety barrier systems, from guardrails to earth berms to median barriers to energy absorbing barriers and mires. However, highway designers have also recognized that safety barriers are hazards in themselves, misfits in the highway environment, and that they are items to be eliminated wherever possible. In a study of fatal accidents on the Interstate Highway System, it was found that fixed object collisions have been the leading source of fatalities, accounting for 43 percent …

Characteristics Of Outdoor Recreational Travel, Jerry G. Pigman, John A. Deacon, Robert C. Deen

Kentucky Transportation Center Research Report

The purpose of this investigation was to examine the characteristics of travel to outdoor recreational areas in Kentucky. Data were obtained by means of a license-plate, origin-destination survey at 160 sites within 42 recreational areas and by means of a continuous vehicle counting program at eight of these sites. A computer algorithm was developed for error detection and subsequent adjustment of the volume data as necessitated by occasional malfunction of the traffic recorders and vandalism. Vehicle occupancy was found to depend of the type of recreational area, distance traveled, and vehicle type. Occupancy increased with increasing distance and was greatest …

Tar Concrete Pavement Construction And Performance, Jerry G. Rose

Kentucky Transportation Center Research Report

In 1969, a 6.6-mile section of relocated KY 15 in Perry and Knott Counties was paved utilizing coal-tar (RT-12) concrete base and surface. This project was authorized under the Appalachian Regional Development Act of 1965 and was designated as experimental as a means of implementing a section of the Act.

Two nearby sections of KY 15, containing asphalt (PAC-5) concrete base and surface, were designated as control sections and used for comparison purposes. With the exception of the bituminous material, the experimental and control sections were purposefully made equal in all other respects. A design soil CBR of 9 was …

Mercury-Filled Settlement Gage, Tommy C. Hopkins, Robert C. Deen

Kentucky Transportation Center Research Report

A description is given of a remote sensing, multiple-point, mercury-filled settlement gage designed for measuring in-place settlements. The gage consists of settlement units positioned at locations where settlement measurements are desired and a monitoring unit located outside of construction limits. Settlement readings are observed on a mercury manometer located at the monitoring site and are· equal to the differences in initial and subsequent pressure head readings. Comparisons of measurements obtained at a highway construction site from mercury gage settlement units and conventional settlement platforms are presented and show very good agreement. With the mercury gage, a large amount of settlement …

Elements Of Median Design In Relation To Accident Occurrence, Gordon R. Garner, Robert C. Deen

Kentucky Transportation Center Research Report

The purpose of this study was to compare the accident histories of different median types and to provide verification of generally recommended median widths and slopes. A major limitation of the analyses was the small number of possible combinations of median width and cross slope available for study.

The analyses reported provided evidence from accident histories to support the general requirement that wider medians are safer medians. It was indicated that medians should be a minimum of 30-40 feet wide for high speed facilities and that flat slopes should be provided; 4:1 slopes are inadequate for medians less than 60 …

Energy Absorption Devices, James H. Havens

Kentucky Transportation Center Research Report

An ironic consequence of modern highways has been the emergence of new types of accidents. Recent investigations (1) have shown that "running off the road" may be the largest, single cause of fatalities on limited access, multilane roads. According to the 1967 Report of the Special AASHO Traffic Safety Committee ("Yellow Book") (2) the rate of accidents in gore areas is approximately four times that of ran-off-the-road accidents at other locations. Gore areas which are not or cannot be modified to provide favorable terrain and unobstructed recovery zones have been recognized as misfits in the environs of the highway. Crash …

Accident And Economic Analyses Of Access Control On Several Bypasses, Kenneth R. Agent

Kentucky Transportation Center Research Report

In an effort to relieve congestion on urban streets, bypasses have been built to provide through traffic a route by which the downtown areas can be avoided.

In many cases, though, bypasses have created a serious accident potential because they were built with at-grade intersections and no access control. This leads to commercial developments along the bypass and congestion at major intersections. Bypasses were constructed in this manner because of the high initial cost involved in building a bypass with access control and grade-separated interchanges. There is, therefore, a need to determine if the accident cost savings, along with time …
