A numerical wave tank based on coupled potential flow-viscous flow model

Creator:: Zhang, Yi
Abstract:: In this study, a coupled potential flow-viscous flow model is used for numerical wave tank simulation. The solver satisfies all the requirements for such a simulation environment. The coupling scheme is based on a non-overlapping heterogeneous domain decomposition method. In this method, the flow domain consists of two subdomains. In...

Seismic Performance of Retrofitted Reinforced Concrete Columns Including Soil Structure Interaction

Creator:: Parson, Lance
Abstract:: There are many existing bridges around the world that were designed without consideration for seismic effects. Many of these bridges were designed before modern earthquake engineering design standards and practices existed and thus are expected to perform poorly during strong ground shaking. Common structural deficiencies are found in their reinforced...

Networked Multi-agent Modeling of Connected Vehicles in Mixed Traffic Environment: A Decentralized Consensus Approach

Creator:: Wahid, Merih
Abstract:: Transportation systems are facing safety and operational challenges with a cost of billions of dollars annually in lost production time and wasted fuel. Infrastructure expansion, previously held as a panacea to most transportation challenges has lost its appeal due to financial, land-use and environmental constraints. Interest is surging in intelligent...

Pore Water Pressure Response in Soil During Tsunami Loading : Numerical Formulation and Experimentation

Creator:: Abdollahi, Abbas
Abstract:: Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Tsunami run-up causes the...

New Rating Methods for Pin and Hanger Assemblies in Steel Bridges

Creator:: Montgomery, Jacob R.
Abstract:: Pin and hanger assemblies are a common type of connection used in past engineering practice for steel girder bridges. The connection consists of pins, hanger plates, and girder ends. The connection detail was used widely between 1930 and 1980. The connections are considered fracture critical and nonredundant because connection failure...

An evaluation of gap acceptance behavior at unsignalized intersections

Creator:: Nabaee, Sahar
Abstract:: Gap acceptance behavior is critical to the safety and operational performance of unsignalized intersections. The complex nature of the human behavior and its dependence on various socioeconomic and environmental parameters makes it challenging for transportation professionals to assess the performance of such intersections. To investigate the behavioral patterns of drivers...

In-plane Creep Behavior of Cross-laminated Timber and Mass Plywood Panels: A Methodology to Evaluate the Long-term Performance of Post-Tensioned Mass Timber Walls

Creator:: Longman, Ryan P.
Abstract:: Post-tensioned (PT) self-centering shear walls were designed to reduce structural damage from seismic activity. However, these lateral force resistant systems experience post-tension loss negatively affecting the re-centering capability due to delayed deformations experienced by engineered wood products over time. The long-term mechanical response of mass-timber panels to in-plane PT loads...

An Agent-Based Simulation for Emergency Warning Dissemination in a Multiplex Social Network

Creator:: Koll, Charles D.
Abstract:: The variety of natural disasters provide different sets of characteristics and properties with unique challenges. One significant difference between hazard types is prewarning lead time, the amount of time individuals have from a potential warning to the disaster occurring. Rapid onset disasters may not provide an official warning about a...

Digitalization of Construction-Phase Information Management by Project Owners

Creator:: Jahanger, Qais K.
Abstract:: Construction is a strategically important industry and its productivity has a significant impact on a nation’s economy. However, productivity in the US construction industry has been widely reported to be on the decline. Among several causes identified, the lack of innovation in project management practices has been described as having...

Optimization of Construction Equipment Efficiency and Cost using Simulation and Field Data

Creator:: Kumar, Deepak
Abstract:: Unlike other industries, overall efficiency of construction projects has been growing minimally which directly causes cost overruns of projects. Though reducing idle time and increasing operational efficiency of construction equipment could result in significant cost saving, there is lack of practical knowledge of adjusting operational efficiency and integrating cost and...
