A Hydrological Characterization Of A Zero-Order Basin In Volcanic Hillslope Terrain, Neil A. Mock May 1988

A Hydrological Characterization Of A Zero-Order Basin In Volcanic Hillslope Terrain, Neil A. Mock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hydrologists have displayed a renewed effort towards understanding the complexity of runoff generation and its association with basin structure. Basin structure is defined as the complex geomorphological, vegetation, and soil characteristics that make up and distinguish the physical nature of a drainage basin. Zero-order basins are an integral part of watershed structure because they furnish the capacity to store and transmit snowmelt and rainfall. By definition, zero-order basins are sub-basins which are depressions in the surf ace and shallow bedrock topography. This study involves a space time characterization of a zero-order basin in fractured media located in southwest Idaho.

Use Of Latex Modified Concrete For Repairs And Overlays, Chen-Hoang Lo Jan 1988

Use Of Latex Modified Concrete For Repairs And Overlays, Chen-Hoang Lo

Theses

Latex modified concrete and polymer concrete have been widely used for bridge deck overlays and crack repairs for the past decade. In recent years, many of these repaired structures were found to be defective. The causes of these failures are not clearly confirmed. Some blame the quality of the latex products while manufacturers accuse the contractors of improper placement and/or surface preparation. While most of these failures largely appeared to be debonding and delamination of the overlays, excessive cracks, possibly shrinkage cracks, were also reported in the overlaid LMC.

To evaluate the suitability of using latex modified concrete for crack …


Column Base Plate Under Eccentric Loading, Ja-Pung Sheu Jan 1988

Column Base Plate Under Eccentric Loading, Ja-Pung Sheu

Theses

The understanding of the strength and deformational behavior of column base plates is of paramount importance in the analysis and design of pipe and pressure vessel supports. Both elastic and plastic stress analyses, using ANSYS computer program to simulate the strength and deformation of column base plates anchored over a concrete block with an eccentric load, are presented in this study. The work presented here includes the effects of bolt pretension and prying actions of stressed flexible plates.

The analytical results were benchmarked with the published test data by D.P. Thambiratnam and P. Paramasivam for the maximum longitudinal strain along …


Reliability Of Existing Bridge Inspection And Evaluation Procedures, Leroy R. Klouser Jan 1988

Reliability Of Existing Bridge Inspection And Evaluation Procedures, Leroy R. Klouser

Theses

In general, bridge inspection is subjective since visual observation and the basic inspection tools cannot reveal hidden structural deterioration, such as corrosive and delaminated rebars embedded in the concrete. Based on the NJDOT SI&A report, a scale (9 to 0) is used in rating five bridge components. This approach seems reasonable, since the time span, manpower and cost are limited throughout the counties of New Jersey. On the other hand, based on the scaling system, the SI&A reports can vary depending upon the exposed surface appearance and the experience of the bridge inspector.

Water, de-icing agents, freezing and thawing cycles …

Behavior Of Reinforced Loess Specimens Under Triaxial Load, Mohammad Taghi Izadi Jan 1988

Behavior Of Reinforced Loess Specimens Under Triaxial Load, Mohammad Taghi Izadi

Masters Theses

"Effects of reinforcement on shear strength of a loessial (silty) soil arc studied. Unconsolidated undrained triaxial tests are performed on unreinforced and fabric reinforced soil specimens. Analyses of the test results showed that in general the shear strength of remolded loess specimens were improved substantially and increase in the shear strength was directly related to reinforcement spacing.

The mechanism of soil-reinforcement interaction and several existing analytical models are described. A modified analytical model based on enhanced confining theory is developed. This model can be used in assessing the effects of the reinforcement on shear strength of triaxial specimens. Comparison of …
