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 ...
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 ...
Calculated versus measured static capacity for two pile types
(University of Missouri--Columbia, 2018)
The Missouri Department of Transportation decided to replace two bridges in northeast New Madrid Country, Missouri. The bridges were in service for approximately 50 years and both were founded on driven piles. The bridge ...
Evaluation of hybrid anchor system for blast resistant steel stud wall design
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Steel stud wall systems are a common building material known for their low cost and ease of construction. However, standard building practices cause ...
Decision support for slope construction and repair activities: an asset management building block
(University of Missouri--Columbia, 2008)
The objective of this research was to develop a support system to facilitate appropriate decision making for construction, maintenance, and repair of earth slopes along transportation rights of way. The system was to be ...
Fluorescence spectroscopy and parallel factor analysis of waters from municipal waste sources
(University of Missouri--Columbia, 2007)
Excitation-emission matrix (EEM) fluorescence spectroscopy is becoming a valuable tool for studying the complex nature of dissolved organic matter. EEMs can identify fluorescence emitting organic substances (fluorophores) ...
Removal of hexavalent chromium and sulfamethazine by green zero valent iron nanoparticles (NZVI)
(University of Missouri--Columbia, 2019)
A green and low-cost method for nZVI fabrication was developed in this thesis using FeCl3 as the source of iron and yerba mate (Ilex paraguariensis) extract as the reductant. The extract showed an impressive high content ...
Replication of freeway work zone capacity values in a microscopic simulation model
(University of Missouri--Columbia, 2008)
Evaluating the traffic impacts of work zones is vital for any transportation agency for planning and scheduling work activity. Traffic impacts can be accurately estimated using microscopic simulation models due to their ...
Locks on deep waterways
(University of Missouri--Columbia, 1900)
Being an outline of the course pursued in the investigation of the proper shape, size, and strength of the walls, floors, miter-walls, &c for locks on Deep-Waterways, built to accommodate Lake and Ocean going vessels, of ...
Determination of probabilistic models for resistance of Missouri bridges
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As part of an overall project sponsored by MoDOT to calibrate the live load factor considering the typical bridge configurations in Missouri and ...
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 ...
Axial load transfer in large scale physical model drilled shaft foundations
(University of Missouri--Columbia, 2019)
Drilled shaft foundations are a widely implemented type of deep foundation used to support heavy loads from superstructures such as buildings and bridges. Uncertainties exist in the axial load transfer behavior of drilled ...
Non-destructive evaluation of wood utility poles using computed axial tomography imaging
(University of Missouri--Columbia, 2006)
Of the more than 130 million wooden utility poles in service, there are approximately 2 million that are replaced annually. A quick, yet accurate non-destructive method of evaluation of the in-service poles could provide ...
Analysis and design of reinforced concrete wall systems for blast
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Building envelope is the first and most critical line of defense for a structure against external explosion. Building envelope can be divided into two ...
Aquatic toxicity of one dimensional carbon nanomaterials
(University of Missouri--Columbia, 2010)
This study determined the toxicity of one dimensional carbon nanomaterials (CNMs) to amphipods, midge, oligochaetes and juvenile mussels in water and sediment. As-produced or modified carbon nanotubes (CNTs) and silicon ...
Investigation of smart work zone technologies using mixed simulator and field studies
(University of Missouri--Columbia, 2020)
Safety is the top concern in transportation, especially in work zones, as work zones deviate from regular driving environment and driver behavior is very different. In order to protect workers and create a safer work zone ...
Development and application of vegetative buffer width modeling using geographic information systems
(University of Missouri--Columbia, 2009)
It has been widely accepted that vegetative buffers are effective in removing nonpoint source pollutants. However, problems focusing on vegetated buffers studies remain, especially in technical aspects (i.e., how to design ...
Federated multimodal simulators in transportation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As transportation involves a multiplicity of modes, there is a need to explore multimodal simulators in transportation and the integration of multimodal ...
