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 ...
A constitutive model for fiber-reinforced soils
(University of Missouri--Columbia, 2007)
Fiber inclusion to improve the properties of compacted soil is becoming increasingly common in geotechnical engineering projects. However, the technique requires extensive testing on soil and fiber samples before it can ...
Methodology to optimize for pedestrian delay and vehicular delay in a signal network
(University of Missouri--Columbia, 2004)
Efficiency of an arterial network could be enhanced by optimizing the user costs of the network incurred due to delay and other socio-economic factors. Until recently, research mostly focused on minimizing vehicular delay ...
Study of the horizontal-to-vertical spectral ratio (HVSR) method for characterization of deep soils in the Mississippi Embayment
(University of Missouri--Columbia, 2009)
Soil deposits can significantly influence the amplitude and frequency content of surface ground motions during earthquakes. Estimating the fundamental frequency (f0) of a site is often needed for improved planning and ...
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 ...
Use of fluorescence excitation emission matrix spectroscopy for water and wastewater characterization
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Excitation Emission Matrix Spectroscopy (EEMS) has the potential to be used for the real time monitoring of environmental effects on water and ...
Analytical and experimental evaluation of steel sheets for blast retrofit design
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Blast resistant design has come to the forefront of engineering concerns in the wake of recent terrorist threats to the United States. The focus of ...
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 ...
Arsenic rejection by membrane processes : model development and application
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated the rejection of arsenic by several nanofiltration and inorganic clay membranes. Laboratory-scale experiments were conducted ...
Occurrence and modeling of THMS and HAA formation in drinking water
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Trihalomethanes (THMs) and haloacetic acids (HAAs) are two of the largest classes of disinfection by-products (DBPs) during chlorination in drinking ...
Environmental effects on subsurface defect detection in concrete structures using infrared thermography
(University of Missouri--Columbia, 2009)
Deterioration of concrete due to corrosion of embedded steel reinforcing bars and prestressing strands represent a significant challenge for inspection and maintenance engineers. Cracking, delaminations and spalling that ...
Data uncertainty in bridge management
(University of Missouri--Columbia, 2006)
The effectiveness of bridge management decisions is based on the quality of data, and the data collected has some amount of uncertainty, which may impact management decisions. This document describes a two-part procedure ...
Analysis of radio communication towers subjected to wind, ice and seismic loadings
(University of Missouri--Columbia, 2006)
The MoDOT radio communication tower network was created in the 1950s and 1960s. There is a need to assess the condition of the towers in the network and also to determine if they are up to date with current codes. A condition ...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to ...
Blast retrofit design of CMU walls using polymer sheets
(University of Missouri--Columbia, 2006)
Many materials have been tested for blast retrofit design but have shown to have limitation. The focus of this research is the analysis of polymer sheets as a method for retrofit design. There are many advantages of polymer ...
Load transfer in micropiles for slope stabilization from tests of large-scale physical models
