A static model for predicting disrupted network behavior
(2010-08)
This thesis compares actual and perceived travel times and presents a model for predicting traffic flows when there is a network disruption. The goal of this research is to demonstrate the necessity of accounting for ...
Strength, stiffness, and damage of reinforced concrete buildings subjected to seismic motions
(2016-05)
Current analytical tools were calibrated mainly using pseudo-static experimental investigations of individual structural components. Relatively few tests have been performed on reinforced concrete structural systems under ...
Analysis of the shear behavior of prestressed concrete spliced girders
(2016-08)
Implementation of the spliced girder technology in bridges has been growing in recent years. Increased girder lengths can now be realized by splicing shorter precast segments to produce a long span. The research conducted ...
Seismic analysis of a retrofitted reinforced concrete building in Mexico City
(2019-08-16)
This thesis presents a study on the dynamic characteristics and seismic performance of a retrofitted concrete building located in the soft soil area of Mexico City. The original structure consisted of reinforced concrete ...
Indoor residential fate model of phthalate plasticizers
(2010-12)
A three-compartment model is extended to estimate the fate and transport of DEHP in a realistic residential environment. The model considered eight environmental media (i.e. air, particulate matter with six size fractions, ...
Hydrological connectivity in vegetated river deltas : the effects of spatial variability and patchiness on channel-island exchange
(2018-05-04)
River deltas are threatened regions of great societal and environmental importance, and their continued survival depends upon a greater understanding of their formation and evolution. Hydrological connectivity in river ...
Removal of inorganic contaminants and natural organic matter by enhanced alum coagulation : defluoridation at the pilot scale and application to arsenic
(2016-12)
The removal of inorganic contaminants is a primary concern in drinking water treatment. Fluoride and arsenic both naturally occur in ground and surface waters throughout the world. Recent health concerns regarding extended ...
Impact of emerging water scenarios on performance of urban water networks
(2018-05-04)
Concerns over the impacts of urban growth have prompted the development and adoption of water-demand management strategies. Water and energy savings from increasingly efficient technologies, diversified water sources, and ...
Chemical usage and savings at the Austin Water Utility drinking water treatment plants
(2012-05)
The goal of this research was to maintain excellent water quality at reduced chemical operations cost. Chemical usage data at the Austin water treatment plants were examined by identifying trends and investigating suspected ...
Analysis of spatial variability in geotechnical data for offshore foundations
(2010-12)
Deep foundations, such as piles and suction caissons, are used throughout an offshore oil and gas production facility in deepwater. Ideally, the values of geotechnical properties for foundation design are determined by ...
