Civil, Construction and Environmental Engineering Publications

In their pavement management decision-making processes, U.S. state highway agencies are required to develop performance-based approaches by the Moving Ahead for Progress in the 21st Century (MAP-21) federal transportation legislation. One of the performance-based approaches to facilitate pavement management decision-making processes is the use of remaining service life (RSL) models. In this study, a detailed step-by-step methodology for the development of pavement performance and RSL prediction models for flexible and composite (asphalt concrete [AC] over jointed plain concrete pavement [JPCP]) pavement systems in Iowa is described. To develop such RSL models, pavement performance models based on statistics and artificial ...


2-D Non-Linear Finite Element Analysis Of Folsom Dam: Seismically Induced Separation And Pore Pressure Along The Soil-Concrete Interface, Grace Amoussou May 2020

2-D Non-Linear Finite Element Analysis Of Folsom Dam: Seismically Induced Separation And Pore Pressure Along The Soil-Concrete Interface, Grace Amoussou

Master of Science in Civil Engineering Theses

The seismic soil-concrete interface stability of composite dams has been an area of interest to many researchers. However, the true interface behavior during a seismic event has not been well understood. During a ground shaking, bonding and de-bonding action along the interface may cause significant separation of soil and concrete surfaces, and such a separation may take place at any depth along the interface creating a stability concern for the overall dam. Moreover, the repetitive nature of bonding/debonding behavior may induce excess pore pressure along the interface, which in turn, may trigger a liquefaction failure or a hydraulic fracture ...

The soil under investigation was laboratory-compacted kaolinite clay mixed with pyranine dye. These specimens were placed beneath an ultraviolet light and a halogen illuminator where reflectance values were collected over a 24-hour period. Correlations were developed from the following methods: 1) spectral indices, 2) continuum analyses ...


Applying Performance Engineered Mixture Design To Permeable Concrete, Rachel Pohl May 2020

Applying Performance Engineered Mixture Design To Permeable Concrete, Rachel Pohl

Civil Engineering Undergraduate Honors Theses

The scope of research and application related to permeable pavements has recently broadened. The desire to significantly reduce the environmental impact of large paved areas makes the permeable pavement concept more desirable (American Concrete Institute, 2018). Although research and interest are increasing, the actual application of permeable pavement is still very limited and has not reached the airfield arena. In airfields, permeable pavement could possibly be used for aircraft aprons - which currently require substantial measures to control stormwater runoff. Permeable pavements are typically used in low-traffic-volume / lightly loaded applications; questions remain regarding a permeable pavement’s ability to hold the ...


Design Wind Loads For Air-Permeable Multilayer Cladding Systems, Connell S. Miller Apr 2020

Design Wind Loads For Air-Permeable Multilayer Cladding Systems, Connell S. Miller

Electronic Thesis and Dissertation Repository

Monetary losses from severe wind storms continue to rise despite improvements to building codes. This is because air-permeable multilayer cladding systems such as vinyl siding and roof pavers are a major component of the monetary losses in severe wind storms, but there are not legal requirements for these products. Some air-permeable multilayer products have manufacturing standards that deal with design loads by eliminating the cavity flow and applying a pressure equalization factor to account for the reduction in net load caused by this cavity flow. The objective of this thesis was to develop design guidelines for wind loads on air-permeable ...

In response, this thesis applies recent research in the fields of landscape architecture and civil engineering to propose a dynamic, natural-systems solution for wetland creation and shoreline protection. The project envisions a series of breakwater-like structures in western Lake Pontchartrain positioned to slow water released from the nearby Bonnet Carré Spillway, causing suspended sediment to settle and create self-building and self-sustaining wetlands capable of keeping pace with ...


Quantification Of Thermal Bridging Effects In Cold-Formed Steel Wall Assemblies, Divyansh Kapoor Apr 2020

Quantification Of Thermal Bridging Effects In Cold-Formed Steel Wall Assemblies, Divyansh Kapoor

Masters Theses

Thermal bridging can be defined as the phenomenon where a structural element spanning the building envelope acts like a thermal pathway which collects and moves energy (heat) from the interior to the exterior of the structure. CFS construction, due to the high thermal conductivity of steel with respect to its surrounding structural components and repetitive nature of framing, is highly prone to thermal bridging. Thermal bridging significantly alters the thermal performance of wall assemblies.

Hence, the objective of this research project was to quantify the magnitude of energy loss through cold-formed steel (CFS) stud wall assemblies at a component level ...

Evaluation Of Coordinated Ramp Metering (Crm) Implemented By Caltrans, Amir Molan, Nivedha Murugesan, Alireza Shams, Cristina Tortora, Faridur Rahman, Jacky Loh, Anurag Pande Apr 2020

Evaluation Of Coordinated Ramp Metering (Crm) Implemented By Caltrans, Amir Molan, Nivedha Murugesan, Alireza Shams, Cristina Tortora, Faridur Rahman, Jacky Loh, Anurag Pande

Mineta Transportation Institute Publications

Coordinated ramp metering (CRM) is a critical component of smart freeway corridors that rely on real-time traffic data from ramps and freeway mainline to improve decision-making by the motorists and Traffic Management Center (TMC) personnel. CRM uses an algorithm that considers real-time traffic volumes on freeway mainline and ramps and then adjusts the metering rates on the ramps accordingly for optimal flow along the entire corridor. Improving capacity through smart corridors is less costly and easier to deploy than freeway widening due to high costs associated with right-of-way acquisition and construction. Nevertheless, conversion to smart corridors still represents a sizable ...


Eliminating Rebar Splicing In Transverse Joints Of Precast Full Depth Bridge Deck Panels, David Gee Apr 2020

Eliminating Rebar Splicing In Transverse Joints Of Precast Full Depth Bridge Deck Panels, David Gee

Civil and Environmental Engineering Theses, Dissertations, and Student Research

This study looks at the removal of longitudinal rebar splicing when sufficient longitudinal post-tensioning is provided for full-depth precast deck panels for simply supported bridges. Full-depth precast prestressed concrete deck panels are high quality plant produced pretensioned panels. They are often post-tensioned at the site to provide an average net compression in the joint of at least 250 psi due to effective prestress. This is to ensure adequate transfer of load as truck wheels pass over the joint. This net compression on the transverse joint is not explicitly clear by the AASHTO LRFD Bridge Design Specifications. Based on this section ...


Monitoring The Performance Of Green Infrastructure: Pervious Pavement And Bioretention, Elizabeth Marie Regier Apr 2020

Monitoring The Performance Of Green Infrastructure: Pervious Pavement And Bioretention, Elizabeth Marie Regier

Master's Theses (2009 -)

Milwaukee, like many other aging cities, struggles with combined sewer overflows, basement backups, and urban stream syndrome. It is increasingly looking to green stormwater infrastructure as a way to alleviate stormwater concerns by treating, retaining, and slowly releasing stormwater near the locations where it falls. However, green stormwater infrastructure varies in its performance, and few studies have been performed in Southeast Wisconsin. Therefore, two bioswales and a pervious pavement installation were monitored for water quantity, total nitrogen, total phosphorus, and total suspended solids. The bioswales were also monitored for dissolved phosphorus. The north bioswale reduced total phosphorus concentrations by a ...
