Identification Of Shales, Tommy C. Hopkins, Robert C. Deen

Kentucky Transportation Center Research Report

Engineering tests were performed on 40 different types of shales. Both hard and soft shales, as well as shales having histories of embankment failures and shales having little known involvements, were tested. The suitability of ten different slake-durability test procedures were evaluated as a means of broadly characterizing the engineering performance of Kentucky shales. Two procedures devised during the study appeared to better characterize slake-durability properties than procedures previously proposed. Natural water contents and jar slake tests were performed to determine if such tests might provide a fairly rapid means of identifying troublesome shales. The natural water content of a …

User’S Manual For Dynamic Programming For Highway Safety Improvement Program, Jesse G. Mayes, Joseph D. Crabtree

Kentucky Transportation Center Research Report

The term, dynamic programming, was first used by Bellman to represent the mathematical theory of a multistage decision process. Dynamic programming is applied to allocate expenditures so that maximum benefits result. Three types of applications of dynamic programming are single-stage, multistage, and multistage with a time factor. Single-stage programming is used to evaluate a single project having several alternatives. Multistage programming involves selection of several projects having several alternatives. Multistage dynamic programming with a time factor is used where several projects and alternatives are considered and where various time periods are involved.

Analysis And Stability Of Closed Surge Tanks, John Emory Fowler

Civil & Environmental Engineering Theses & Dissertations

The equations representing the water surface oscillations in a closed surge tank form a set of nonlinear ordinary differential equations when the system is considered as lumped. Because of the nonlinear terms present in the equations, a closed-form solution of the equations is not available. Several numerical methods ranging from single step methods to higher-order multi-step methods were used to find numerical solutions to the governing equations. As all the methods required a similar amount of CPU time, the degree of accuracy required would determine which numerical method should be used. The effect of various system parameters on the stability …

Behavior Of Channel-Shaped Reinforced Concrete Columns Under Combined Biaxial Bending And Compression, Dureseti Chidambarrao

Theses

The inelastic behavior of irregular shaped reinforced concrete columns has been a constant concern for a structural engineer, to design a safe and economic structure in modern buildings and bridge piers. The shape of the elements in a reinforced concrete structure may be used to optimize its structural strength, to make better use of the available space, to improve the aesthetic appearance of the structure, or to facilitate construction. Due to the locations of the columns, the shapes of the buildings and the nature of the applied loads, many columns are subject to combined biaxial bending and axial load.

Seven …

Failure Surface For L-Shaped Reinforced Concrete Short Columns, Mon-Chen Liu

Theses

Combined bending and axial compression for L-shaped reinforced concrete short columns is a common problem. But the present ACI Building Code (ACI 318-77), handbooks and texbooks pay no attention to this problem. A numerical analysis and computer program developed by Hsu fora reinforced concrete member subject to biaxial bending and axial load has been used Using this computer program, the interaction diagrams and failure surface were developed for L-shaped members under combined bending and axial compression. A comparison between theoretical and experimental results was included to examine the validity of failure surface.

Analysis And Tests [Of] L-Shaped Reinforced Concrete Column Under Combined Biaxial Bending And Axial Compression, Alaedin Majlesi

Theses

A total of five tests on biaxially loaded column specimens were conducted to investigate the complete behavior of load-deformation characteristics from zero load until failure. The specimens were tested under horizontal position with 60 ton hydrolic jack. Pin end was used for both ends to obtain higher accuracy of plotting curves.

Two specimens were tested with dial gages to obtain load-deflection curves and the other three specimens were tested with demec and strain gages to obtain load strain and moment-curvature curves. The strain gages were measured by weston bridge and deme-gages were measured by mechanical dial gage.

The above moment-curvature …

A Checklist And Sample Specifications For Front End Loaders, Herpicc

Indiana Local Technical Assistance Program (LTAP) Publications

Attached is a checklist and sample specifications for purchasing front end loaders for use in the maintenance of Indiana's local roads and streets.

This checklist and the sample specifications provide for individual preferences. They are not intended to dictate decisions or restrict bidding. If followed, they will assure a durable piece of maintenance equipment well suited for the uses placed on front end loaders by Indiana Counties, Cities and Towns.

A general observation of those with experience is that reducing specification requirements to obtain a lower first cost is nearly always a poor economic decision.
