Experimental and analytical evaluation of disproportionate collapse flat-plate buildings
(University of Missouri--Columbia, 2015)
Reinforced concrete flat plate buildings without continuous integrity reinforcement may be vulnerable to disproportionate collapse if a supporting structural member was lost in an abnormal event. This research forces on ...
Applications of activated carbon to reduce disinfection byproducts in small drinking water systems
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The addition of chlorine disinfectant to drinking water during the treatment process results in the formation of disinfection by-products (DBPs). The ...
A study of ADA public rights-of-way accessibility guideline impacts
(University of Missouri--Columbia, 2013)
The aim of this research is to improve safety and mobility for the disabled community by examining the impacts of the Public Rights-of-Way Accessibility Guidelines (PROWAG). Another aim is to identify the economic consequent ...
Evaluation of tensile and compressive membrane action in isolated slab column specimen
(University of Missouri--Columbia, 2012)
Older flat-plate buildings are susceptible to progressive collapse in which the failure of one slab-column connection can propagate to other connections and cause a full collapse of the building. The most common mechanism ...
Novel methods for preparation of modified 1-dimensional nanomaterials of titanium dioxide for environmental engineering applications
(University of Missouri--Columbia, 2012)
Photocatalytic processes of titanium dioxide have been discovered in the early 1980 and till now titanium dioxide nanomaterials are the most popular photocatalysts for scientific researches and industrial applications. In ...
Maximizing information for evaluation of incident management systems with an emphasis on secondary accidents
(University of Missouri--Columbia, 2011)
Incident management is the process of mitigating the effects of traffic incidents via quick and effective response, thus reducing the congestion and the potential for secondary accidents. The evaluation of incident management ...
Evaluation of wearing surface systems for the orthotropic steel deck of the San Mateo Hayward Bridge
(University of Missouri--Columbia, 2012)
Performance under static and fatigue loads are evaluated for two different wearing surfaces for possible use on the steel orthotropic deck of San Mateo Hayward Bridge in the bay area of California. The two wearing surface ...
Shear strength of flue gas desulfurization by-product
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Shear strength parameters of flue gas desulfurization (FGD) sludge were investigated by conducting a series of constant volume direct simple shear tests ...
Uncertainty propagation and parameter sensitivity analyses of relative permittivity models for use in soils
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nondestructive subsurface investigations are becoming more popular in geotechnical engineering ranging from agricultural applications to environmental ...
Red light running at traffic circles: estimation and evaluation of countermeasures effectiveness
(University of Missouri--Columbia, 2013)
The complicated legacy design of traffic circles results in operational and safety deficiencies. This type of intersection design is commonly used at major roadways in Cochabamba, Bolivia. Traffic circles are intended to ...
Link travel time estimation based on connected vehicle probe data
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Connected vehicle technology is a wireless system to support communication for enhancing safety and mobility. The thesis proposes a single-link connected ...
Verification of thermographic bridge inspection technologies
(University of Missouri--Columbia, 2015)
This paper covers the research performed to determine the reliability of infrared technology as an inspection tool for concrete bridge components. Concrete deteriorates due to the corrosion of embedded reinforcing steel. ...
Reduction of DBP formation potential in drinking water through forced alkaline conditions and aeration
(University of Missouri--Columbia, 2015)
As the United States Environmental Protection Agency (USEPA) moves to the more stringent Disinfection By Product (DBP) Stage 2 rule, small communities are challenged to meet the regulations. According to compliance data ...
Correlation of site variability from SASW and CPT measurements
(University of Missouri--Columbia, 2018)
Geotechnical site characterization programs are designed to reduce uncertainty and maximize the efficiency of geotechnical design. Ironically, however, many site characterization programs are inefficient themselves as they ...
Experimental assessment of advanced thermal imaging for detecting voids in ducts
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This research will evaluate the ability of a transient based Infrared Thermography (IRT) technology called the Infrared Ultra Time Domain (IR-UTD) ...
Implementing data-driven decisions for asset management in local communities
(University of Missouri--Columbia, 2016)
The successful implementation of Transportation Asset management (TAM) by local governments facilitates the optimization of limited resources. The use of a data-driven TAM program helps to identify and prioritize needs, ...
Interchange alternative selection based on analysis of operational measures
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Interchanges are a particularly important focus in transportation because of the high level of interacting cross-traffic. Often, traditional diamond ...
