Channel And Z-Sections Braced By Diaphragms, Nuri Celebi, George Winter

CCFSS Library (1939 - present)

The behavior of thin-walled cold formed channel and Z-sections, braced on their upper flange by light-gage steel diaphragms under static loading is studied. The objective of the study is to obtain mathematical solutions, to verify these solutions by tests, and to derive design formulations for the bending behavior of channel and Z-section beams with various boundary conditions. This type of structural element is encountered as purlins and girts to support the roof cover and siding of metal buildings. The roof cover is connected to the upper flange of the purlins and gives rise to the case of braced compression flange …

A Preliminary Evaluation Of Mounds To Divert Wayward Vehicles Away From Rigid Obstructions, Gordon R. Garner, J. B. Venable

Kentucky Transportation Center Research Report

In the summer of 1965, the first fatality report involving an interstate median bridge pier in Kentucky caused concern among state and national officials for the safety of motorists who perchance or otherwise enter upon a collision course toward an unprotected bridge pier. A consensus of opinion seemed to indicate that some form of attenuation or deflection device was necessary.

Early innovations employed various short guardrail configurations to deflect wayward vehicles from the piers. The use of small, short sections has since evolved until present methods include surrounding the bridge pier with several hundred feet of guardrail, including ramped-end treatment …

Cold-Rolled Austenitic Stainless Steel: Materials Properties And Structural Performance, George Winter, S. T. Wang

CCFSS Library (1939 - present)

The cold reduction in thickness of austenitic stainless steel sheet brings about the following significant characteristics of material properties: 1) higher strength with an increasing amount of cold working, 2) more pronounced anisotropic material properties with increasing cold working, 3) stress strain relations different in tension and compression and depending on directions, and 4) nonlinear stress strain curves with relatively low elastic limits, especially in longitudinal compression. In addition, local buckling is encountered in thin walled structural members. These are the problems associated with the structural design of stainless steel members. The purpose of this investigation is to develop the …

Lateral Distribution Of Traffic On A Four-Lane And Six-Lane Section Of I 75 South Of Covington, Robert L. Lynch, Gary N. Hamby

Kentucky Transportation Center Research Report

With the increased construction of multilane highway facilities in the past few years, the need for establishing corresponding design and traffic operational criteria for these highways has resulted. This is especially true for rural, multilane facilities, since few of these highways are not, as yet, operating at a critical level of traffic service.

One area of traffic operational characteristics that has received very little attention in the past concerns the distribution of vehicles by lane on multilane highways. The capacity for these highways have been defined by the one-directional traffic volume rather than by the individual lane volumes. The distribution …

Analysis Of Traffic Loads On Bridges: Report Ii Characteristics Of Traffic On Ohio River Bridges - 1968, Robert L. Lynch

Kentucky Transportation Center Research Report

The recent bridge disaster at Point Pleasant, West Virginia, has renewed concern about the mechanism of material fatigue as a possible cause of catastrophic failure of bridge structures. A reasonable methodology for evaluating the fatigue condition of the highway bridge requires a knowledge of the distribution of traffic loads utilizing the facility during the analysis period. The accuracy of such an analysis is dependent on the accuracies of the input data -- material fatigue properties and traffic characteristics. The more critical of the above parameters, with respect to accuracy, appears to be traffic characteristics. This is especially true of vehicle …

Rheological And Ultimate Strength Properties Of Cohesive Soils, Gordon D. Scott

Kentucky Transportation Center Research Report

In recent years, there have been considerable advances made in rheological theory and its application to various materials. There has not been, however, nearly as much work done toward applying rheology to soil mechanics as the successes of others would seem to indicate. For instance, it has been shown that a variety of stress and deflection problems considering the application of a load by means of an elastic plate to an elastic foundation can be extended to include rate effects through the application of linear viscoelastic theory. Before this theory can be applied to foundation design, however, two questions must …

Cutthroat Flow Measuring Flumes For Flat Gradient Channels, Gaylord V. V. Skogerboe

Reports

The cutthroat flume can operate either as a free or submerged flow structure. Submerged flow calibration curves and free flow equations have been developed. Rectangular cutthroat flume sizes of 1, 2, 3, 4, and 6 feet were studied and tested in the laboratory. Trapezoidal cutthroat flumes having zero (or V-shaped), 6-inch, and 12-inch throat widths were calibrated. The value of transition submergence is listed for each of the rectangular and trapezoidal cutthroat flumes. The most obvious advantage of a cutthroat flume is economy, since fabrication is facilitated by a flat bottom and removal of the throat section. Another advantage is …

A Study Of The Correlation Potential Of The Optimum Moisture Content, Maximum Dry Density, And Consolidated Drained Shear Strength Of Plastic Fine-Grained Soils With Index Properties, Marvin Tartt Harris

Masters Theses

"The correlation potential of the compaction properties and the consolidated drained shear strength parameters of plastic fine-grained soils with index properties was investigated in this study. The interrelationships of these properties were derived through graphical and multilinear regression analysis. The compaction properties, optimum moisture content, and maximum dry density were found to be related to many of the index properties. The most important relationships were with the plasticity indices and the percentage of particles smaller than two microns; the highest degree of simple correlation was achieved with the liquid limit. The consolidated drained shear parameters, cohesion, and the angle of …

Inventory Of Indiana County Bridges, Jean E. Hittle

Indiana Local Technical Assistance Program (LTAP) Publications

The purpose of this report is to bring county bridge needs into focus-state-wide and county-by-county-through a detailed computerized inventory listing of all existing county bridges. Each county's inventory listing has been further summarized as to the number of bridges by length and width categories, along with an estimated replacement cost. This inventory report thus gives a measure and dimension to the county bridge problem. Hopefully this information will assist local road officials, legislative study groups, and members of the General Assembly in weighing alternate solutions to the financing of county bridge programs.

Finite Difference Solutions To Free Jet And Confined Cavity Flows Past Disks With Preliminary Analyses Of The Results, Roland W. Jeppson

Reports

A number of solutions are obtained to ideal axisymmetric flow past cavitating disks for both cases of a free surface jet and flow confined in a constant radius conduit. Finite difference methods are utilized in obtaining the solutions from an inverse formulation which considers the velocity potential, and Stokes’ stream function, as the independent variables and the radial and axial dimensions, r and z, as the dependent variables. The resulting inverse boundary value problem for r, for which the basis solution is obtained, is nonlinear. The solution technique uses a Newton-Raphson iteration to evaluate the implicit finite difference operator at …
