Numerical response of concrete-lined tunnels crossing active faults

Creator:: Lange, Stephanie
Abstract:: A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...

Interactive Genetic Algorithms for watershed planning : an investigation of usability and human-centered design

Creator:: Piemonti, Adriana Debora
Abstract:: Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...

Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

Creator:: Smith, Jeremy A.
Abstract:: High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

Behavior of Steel Structures in Fire Following Earthquakes

Creator:: Maddalozzo, Walker A.
Abstract:: Fire following earthquake (FFE) events are cascading hazards that have caused great damage in the past and pose a continued threat to our communities. The increased risk for fire after a seismic event stems from potential damage to utilities such as gas or fuel pipelines, which can lead to ignition....
Resource Type:: Masters Thesis
Full Text:: temperature (Lange et al. 2014), total compartment fire load (Gernay et al., 2016), radiant heat energy (RHE

Numerical Investigations on Sewer Geysers

Creator:: Choi, YunJi
Abstract:: A sewer geyser is a series of ejecting air-water mixture eruptions through vertical shafts of drainage systems. In field observed geyser incidents, manhole covers were blown into the air and they were followed by ejecting air-water mixture eruptions that lasted for several seconds at a time. Trapped air in sewer...

Integrating Science Needs with Advanced Seafloor Sensor Engineering to Provide Early Warning of Geohazards: Visioning Workshop and Roadmap for the Future

Creator:: Parrish, Christopher E., Mason, H. Benjamin, Trehu, Anne M., Hollinger, Geoffrey A., Selker, John S., and Zhang, Eugene
Abstract:: The workshop was funded by the National Science Foundation (NSF), OCE Division of Ocean Sciences (Award # 1817257). This report summarizes the key findings, outcomes, and recommendations of the workshop and serves as a draft of the comprehensive roadmap.

Owner's Role in Brownfield Remediation : The Brownfield Experts' Perspective

Creator:: Saberiyan, Amireh G.
Abstract:: Former industrial or commercial sites that have been left unused are typically referred to as brownfield sites, or simply, brownfields. Many communities have such properties that are abandoned, idle or underused. Despite public efforts to facilitate brownfields revitalization projects, the rate of remediation remains unexpectedly slow. Efforts to resolve this...

Measuring and Correcting the Electrical Resistivity of Concrete Pore Solution in Fresh Mixtures

Creator:: Biever, Joseph H.
Abstract:: A vital aspect of concrete construction is quality assurance and control (QA/QC). Engineered structures must meet pre-determined and agreed-upon strength and durability requirements. Concrete falls into a specific category of infrastructure material because in most cases, these strength and durability requirements cannot be found until the material has at least...

Identifying and prioritizing research gaps for the incorporation of fires in life cycle analysis of structures: A Delphi survey of international experts

Creator:: Thorp, Tiana Noelani
Abstract:: Civil engineers are aware of the impacts of structures on the global environment but the environmental impacts of a fire within these structures remains unknown. Fires present a unique hazard as it is difficult to predict the probability of the occurrence and the intensity. Traditional methods to identify the environmental...

Investigation of x-ray computed tomography for Portland cement phase quantification

Creator:: Deboodt, Tyler J.
Abstract:: Cementitious materials are often characterized through the use of advanced analytical techniques to understand the macro-, micro-, and nano-scale properties, including phase formation during hydration, and subsequent potential deterioration mechanisms which can affect service life. A major limitation with using such analytical techniques to quantify solid phases in cementitious systems...
