RSS 1.0Department of Civil and Environmental Engineering (MU)
Civil engineering, considered one of the oldest engineering disciplines, encompasses many specialties. The major ones are structural, water resources, construction, environmental, transportation, and geotechnical engineering. Environmental engineers develop solutions to environmental problems using the principles of biology and chemistry. Many environmental engineers work as consultants, helping their clients to comply with regulations, to prevent environmental damage, and to clean up hazardous sites.

Approaches for comparing the structural characteristics of different representations of transportation systems
(University of Missouri--Columbia, 2018)Collection and monitoring of locational information has considerably increased over the last decade as the value of location-based data has been realized by planning organizations and agencies. Global Positioning Systems ... -
Determination of the scale of fluctuation of cone penetration test data obtained from an alluvial site in missouri
(University of Missouri--Columbia, 2018)To account for uncertainty in geotechnical projects, knowledge of the uncertainties should be understood. Many sources of uncertainties can be reduced with increased sampling and good practices, but due to the nature of ... -
Post-construction verification of hydraulic conductivity of soil in an earthen dam
(University of Missouri--Columbia, 2018)Earthen dams are used throughout the country to hold back flood waters from cities, towns, and farmlands, make reservoirs to supply drinking water, and create lakes for recreational purposes. The hydraulic conductivity of ... -
Calculated versus measured static capacity for two pile types
(University of Missouri--Columbia, 2016)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 ... -
Driving simulator use and calibration for work zone merge sign evaluation
(University of Missouri--Columbia, 2018)Work zones on highways have the potential to increase crash risk; therefore, efficient and noticeable signs play a critical role in enhancing highway safety. Some engineers have suggested that the traditional Manual on ... -
Iron oxide-graphene oxide nanocompositions as adsorbents
(University of Missouri--Columbia, 2016)Iron oxides and carbon containing materials are recognized for their potential in the water treatment field as adsorbent materials for removing many contaminations such as heavy metals and organic matter. One of these iron ... -
Advancements in evaluating reliability of nondestructive technologies for the detection of subsurface fracture damage in R.C. bridge decks
(University of Missouri--Columbia, 2017)During the last few decades, many efforts have been made to assess the reliability of nondestructive evaluation (NDE) technologies used for the detection of subsurface damage in concrete bridge decks. During these efforts, ... -
Reliability-based design (RBD) of shallow foundations on rock masses
(University of Missouri--Columbia, 2015)The reliability-based design (RBD) approach that separately accounts for variability and uncertainty in load(s) and resistance(s) can be incorporated into the design of shallow foundations on jointed rock masses resulting ... -
Reliability-based versus allowable stress design of foundations for the Center for Missouri Studies building
(University of Missouri--Columbia, 2017)Uncertainty in design parameters is inherent to the field of geotechnical engineering. Allowable stress design has conventionally been used for foundation design and accounts for uncertainty in geotechnical parameters and ... -
Safety modeling for two certain urban intersection types, HSM calibration, and crash severity distribution
(University of Missouri--Columbia, 2017)According to several years' official crash data, a significant proportion of crashes happened at roadway intersections in Missouri. Of those intersection crashes, a large number of crashes occurred at urban roadway ... -
Progressive damage of multiple bolt connections in thick composite plates
(University of Missouri--Columbia, 2017)Bonded connections are typically preferred for joining composite member. However, when supporting relatively large forces, the thickness and/or size of a composite member can increase, which leads to large forces being ... -
Development of a portable total-stress measurement instrument
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This research explores the application of ultrasonic stress measurement (USM) technologies to assess stress levels in gusset plates with the development ... -
Recent efforts on model-based simulation of engineering problems : multiphysics and multiphase interactions
(University of Missouri--Columbia, 2016)Simulation-Based Engineering Science (SBES) is playing a more important role in gaining new knowledge and providing guidance for engineering activities, in particular, in the fields in which time scale and/or spatial scale ... -
Characterization of adobe wall structural systems for dynamic response
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Adobe building construction exists around the world. Most of the adobe structures are located in active seismic zones, and a considerable amount of ... -
Management of DBP formation using enhanced treatment technologies and an array of prediction tools
(University of Missouri--Columbia, 2017)Inefficient removal of total organic carbon (TOC) leads to the formation of carcinogenic disinfection by-products (DBPs) when a disinfectant is added. This study is performed in an effort to develop a simple, non-invasive ... -
Transportation safety modeling and evaluation: alternative geometric designs, enforcement, and airfield applications
(University of Missouri--Columbia, 2017)A top priority of transportation agencies in the United States is to improve safety of transportation facilities through the use of latest technology, innovative designs, procedural methods, and training practices to ... -
Estimating the rock mass modulus of Missouri shale using pressuremeter tests
(University of Missouri--Columbia, 2017)Rock mass modulus can be a useful property in the design of foundations. Rock mass modulus is defined as the stress strain response of a rock mass in-situ. The stress strain response of the rock mass can be estimated by ... -
Dynamic increase factor in reinforced concrete frames under disproportionate collapse
(University of Missouri--Columbia, 2017)Under a disproportionate collapse, the sudden loss of a support causes a dynamic response that can amplify the internal forces in the surrounding members and lead to significant global damage. This study considered a ... -
