Nov 5, 2021 - CAIT-UTC-REG14: Performance-Based Engineering of Transportation Infrastructure Considering Multiple Hazards
Alexandros Nikellis; Kallol Sett; Teng Wu; Andrew S. Whittaker, 2021, "Data for CAIT-UTC-REG14: Performance-Based Engineering of Transportation Infrastructure Considering Multiple Hazards", https://doi.org/10.7910/DVN/SWZF1S, Harvard Dataverse, V1
A framework is developed for performance-based engineering of transportation infrastructure considering multiple hazards. The framework builds upon the FEMA P-58 methodology for seismic performance evaluation of buildings, but utilizes an event-based approach in a multi-hazard context and considers both structural and downtime losses. The framework... |
Feeley, Cecilia; Lubin, Andrea; Hwang, Jinuk; Tobin, Brian, 2021, "CAIT-UTC-REG 21: Autonomous Vehicles: Capturing In-Vehicle Experience and Focus Group Follow-up with Persons with Autism and Other Disabilities", https://doi.org/10.7910/DVN/GPEBOL, Harvard Dataverse, V1
As autonomous vehicle (AV) innovation continues to gain worldwide momentum and with it the potential for expanded mobility, it is vital to consider how this technology can contribute to improved access for persons with disabilities, who represent one in four U.S. adults, or over 60 million persons. To date, there has been limited research focused o... |
Jul 19, 2021 - CAIT-UTC-REG2B Sustainable, Rapid Repair Using Advanced Cementitious Materials
Ranade, Ravi; Okumus, Pinar, 2021, "Data for CAIT-UTC-REG2B - Sustainable, Rapid Repair Utilizing Advanced Cementitious Materials", https://doi.org/10.7910/DVN/FTNV5O, Harvard Dataverse, V1, UNF:6:yRhGSrwXVHdTrQKdswtUXw== [fileUNF]
Durability and resilience of a structure are typically considered separately, as they address structural performance under different types of loads. A systematic framework for combined durability-resilience assessment of an RC bridge column is presented in this article. Corrosion of steel reinforcement is the main deterioration mechanism considered... |
Mar 24, 2021 - Fire in Tunnel Collaborative Project
Negar Elhami-Khorasani; Anthony Tessari, 2021, "Year 1, 2 report Data", https://doi.org/10.7910/DVN/V6E9S0, Harvard Dataverse, V1, UNF:6:IE9cPGizEXViWNoI6Q7DVA== [fileUNF]
Extreme fire events in tunnels may have catastrophic consequences, which include loss of life, structural damage, and major socioeconomic impacts due to service disruptions. In this report, a traveling fire model for a railway tunnel is established to evaluate the evolution of temperatures considering fire spread between train cars. Uncertainties i... |
Mar 24, 2021 - Seismic Vulnerability Assessment of Deteriorated Bridges
Ravi Ranade; Pinar Okumus, 2021, "Data for UTC Region II Year 2 Ranade-Okumus Final Report", https://doi.org/10.7910/DVN/BPEPAH, Harvard Dataverse, V1, UNF:6:+VgAjNd7TTIqu82m1S+LkQ== [fileUNF]
The seismic vulnerability assessment methods currently used by state DOTs typically rely on as-built conditions of bridges. However, due to environmental deterioration, the structural performance can degrade over time. This research demonstrates the application of a combined durability-fragility assessment framework, developed by the authors, for a... |
Mar 24, 2021 - Real-Time Prediction of Storm Surge and Wave Loading on Coastal Bridges
Teng Wu; Shaopeng Li; Kallol Sett, 2021, "UTC Final Report Data (Locations A and B)", https://doi.org/10.7910/DVN/RNXKDX, Harvard Dataverse, V1, UNF:6:kIMnP+EewoH+WZywGLq8kA== [fileUNF]
Coastal bridges exhibit significant susceptibility to damages caused by storm surges and waves, which requires probabilistic models to quantify the bridge vulnerability for risk assessment and mitigation activities. This study presents an efficient risk analysis framework integrating hazard analysis and fragility analysis for coastal bridges under... |
Jan 19, 2021 - Airfield Pavement Management Framework using a Multi-Objective Decision Making Process
Hao Wang, 2021, "Airfield Pavement Management Framework using a Multi-Objective Decision Making Process", https://doi.org/10.7910/DVN/WCMVOL, Harvard Dataverse, V1, UNF:6:CjpPW1m3KEhlysI9BsDG8A== [fileUNF]
Airfield Pavement Management collects data of structural condition such as fatigue cracking and rutting. However, important factors affect the safety of aircraft operations including non-structural distresses of low friction and surface distortion are missing in the data collection process. The goal of this research is to develop a decision-making... |
Jan 19, 2021 - Sustainability and Resiliency of Concrete Rapid Repairs Utilizing Advanced Cementitious Materials – Freeze/Thaw Loads
Matthew P. Adams, 2021, "Sustainability and Resiliency of Concrete Rapid Repairs Utilizing Advanced Cementitious Materials: Freeze/Thaw Loads", https://doi.org/10.7910/DVN/WIQF68, Harvard Dataverse, V1, UNF:6:eDe1raAkTL1Y5Oe2twOdCg== [fileUNF]
Rapid-repair cements are important to extending the life of infrastructure. Damage occurs to concrete systems because of poor construction quality, accidents, severe environmental conditions, and general wear and tear. Using rapid-repair materials allows agencies to repair the infrastructure without causing undue service delays and without having t... |
