Precast prestressed bridge approach slab : cost effective designs
(University of Missouri--Columbia, 2012)
. The two suggested alternatives are also effective for rapid replacement/repair operations on bridge approach slabs. A life cycle analysis (LCCA) was completed to study comparative costs for urban and rural traffic patterns and to investigate the economic...
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 to optimize user costs...
Remote health monitoring for asset management
(University of Missouri--Columbia, 2009)
This project explored the development of real-time monitoring technology to be used for effective asset management. There is a critical need to develop technologies to assess and monitor the condition of these bridges over ...
Evaluation of the service performance of an innovative precast prestressed concrete pavement
(University of Missouri--Columbia, 2009)
Precast prestressed concrete pavement (PPCP) is the product of an optimization of conventional materials coupled with economical fabrication and transportation means to create a product that exceeds the performance and implementation of current...
Development of solution techniques and design guidelines for equestrian trails on public lands
(University of Missouri--Columbia, 2007)
Increasing equestrian use on recreational trails puts intense pressure on the environment. Horse traffic produces high stresses that can cause trail degradation such as erosion and muddiness. Much is known about causes of ...
Methodology for quantifying wetland landscape parameters for highway right of way decisions utilizing GIS
(University of Missouri--Columbia, 2008)
Wetlands are a type of habitat which forms an interface between aquatic and terrestrial ecosystems. A growing problem in the state of Missouri and around the nation is the loss of the natural wetlands due to the expansion ...
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 ...
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 ...
Evaluation of alternative resistance mechanisms for progressive collapse
(University of Missouri--Columbia, 2011)
of information on how to economically provide that resistance. Reinforced concrete frame structures, however, may possess inherent structural redundancy and ability to withstand collapse if the structure is properly detailed to provide alternative resistance...
Optimization of aeration schemes and motor and blower usage for wastewater treatment
(University of Missouri--Columbia, 2010)
This thesis discusses the control of aeration schemes on a lab sized sequencing batch reactor used for biological wastewater treatment. The focus was changing aeration schemes for two lab reactors and determining which ...
Evaluation of stay-in-place PVC-formed concrete walls for blast design
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In the event of a blast, concrete might not have the toughness needed to absorb the large amounts of energy imparted, even with the moderate steel ...
Nitrification enhancement in lagoons using fixed film media
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Lagoons, commonly used in municipal wastewater treatment, are limited in their ability to treat wastewater due to limitations in the process 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 ...
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 ...
Performance analysis of parallel flow intersection and displaced left turn intersection designs
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The displaced left turn (DLT) (also known as the continuous flow intersection (CFI)) design has proven to be a superior alternative to the conventional ...
