Analytical study of the spectral-analysis-of-surface-waves method at complex geotechnical sites
(University of Missouri--Columbia, 2006)
The Spectral-Analysis-of-Surface-Waves (SASW) method is an accepted means of measuring shear wave velocity (VS). In some settings, SASW measurements have produced results that were inconsistent with results from other ...
Development and implementation of an underwater system for interface wave measurements
(University of Missouri--Columbia, 2005)
Measuring shear wave velocity profiles has become integral to geotechnical site investigation both on land and offshore. Obtaining accurate near-surface profiles in soft marine sediments can be expensive and time consuming ...
Model-based simulations of the piercing process in piezo-ICSI
(University of Missouri--Columbia, 2008)
To develop a piezo intracytoplasmic sperm injection (piezo-ICSI) procedure without using mercury, the real physics behind the zona piercing must be understood. An effort has been made to formulate a three-dimensional model ...
Blast resistant forced entrty [sic] steel stud wall design
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Due to the threat of terrorist attacks, a series of tests has been conducted, on different forced entry wall configurations, to determine the static ...
Instrumentation and early performance of an innovative prestressed precast pavement system
(University of Missouri--Columbia, 2006)
Traffic, weather and de-icing salts continually diminish pavement life. Current rehabilitation methods result in traffic congestion and lost work time. The use of prestressed, precast panels for the replacement of damaged ...
Tensile strength, shear strength, and effective stress for unsaturated sand
(University of Missouri--Columbia, 2006)
It is generally accepted in geotechnical engineering that non-cohesive materials such as sands exhibit no or negligible tensile strength. However, there is significant evidence that interparticle forces arising from capillary ...
Function-based condition indexing for guyed communication towers
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Construction of the Missouri Department of Transportation (MoDOT) two-way radio network was initiated in the 1950's and was motivated primarily by the ...
Load transfer in reticulated and non-reticulated micropiles from large-scale tests
(University of Missouri--Columbia, 2007)
Using micropiles for slope stabilization is a proven technique but there are many uncertainties with how load is transferred from the soil to the structural elements. A large-scale model was constructed to test model slopes ...
Nonlinear finite element modeling and characterization of guyed towers under severe loading
(University of Missouri--Columbia, 2007)
Guyed towers have been widely employed in the telecommunication industry. This study thus intends to improve the understanding and analysis of guyed towers that undergoes not only large deformation, but also large strain. ...
Pattern recognition based microsimulation calibration and innovative traffic representations
(University of Missouri--Columbia, 2008)
Even though calibration techniques for traffic simulation abound, this dissertation presents the first mathematical formalization using representations and invariants. The calibration is defined succinctly over three levels ...
Geotextile wrap-face wall using marginal backfill
(University of Missouri--Columbia, 2006)
A concrete retaining wall was constructed during October/November 2005. The height of the wall was 9 feet with a stem width of 0.83 ft, while the width of the base was 1.83 ft. The backfill was a low plasticity clay (CL). ...
Load transfer in micropiles for slope stabilization from tests of large-scale physical models
(University of Missouri--Columbia, 2006)
The objective of this work is to provide experimental data to improve prediction of limit loads for micropiles in slope stabilization applications. The experimental data were obtained from tests of 1-g model slopes 8 ft ...
Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases ...
