Development Of A Mash Test Level 4 Open Concrete Bridge Rail, Jacob Delone
Development Of A Mash Test Level 4 Open Concrete Bridge Rail, Jacob Delone
Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research
An open concrete bridge rail was designed and developed according to safety performance guidelines in the American Association of State Highway Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) for Test Level 4 (TL-4). Systems designed and developed under previous guidance were studied, and their geometric information and full-scale crash testing performance was studied to establish the geometry of the new bridge rail. Yield-Line Theory and the AASHTO Post and Beam design methods were studied, and a modified version of the AASHTO Post and Beam method was utilized to determine the capacity of the new open concrete bridge rail. …
Beaver Creek Restorative Design Using Engineering In Nature, Lindsay M. Levatino
Beaver Creek Restorative Design Using Engineering In Nature, Lindsay M. Levatino
Senior Honors Projects, 2020-current
Stream restoration work can be instrumental for the wellbeing of an ecosystem. Located in the Shenandoah Valley in Virginia is Beaver Creek, a well-known spot for fly-fishing due to its pristine water conditions and open surroundings. In order to maintain these conditions, a 100-foot stretch of Beaver Creek needed to be restored to prevent further erosion, stabilize the banks, and enhance the natural habitats. The project involved excavating a sediment island, filling in an eroded bank, building a cross vane, and adding stakes. Local stakeholders came together to complete this project contributing their expertise, equipment, and time. The construction was …

Load Truncation Approach For Development Of Live Load Factors For Bridge Rating, Sasan Siavashi, Christopher D. Eamon
Load Truncation Approach For Development Of Live Load Factors For Bridge Rating, Sasan Siavashi, Christopher D. Eamon
Civil and Environmental Engineering Faculty Research Publications
Various local governments have developed state-specific vehicular live load factors for bridge rating. However, a significant computational demand is often associated with such an effort. This is due to the large size of the weigh-in-motion (WIM) databases frequently used in the procedure. In this study, a method is proposed that can significantly reduce the computational cost of the analysis, while still maintaining reasonable accuracy. The proposed approach develops approximate live load random variable statistics by truncating the WIM database based on gross vehicle weight, then a complete reliability analysis is conducted to develop new live load factors that meet AASHTO-specified …
Seismic Response Mitigation Of Base-Isolated Buildings, Mohammad Hamayoun Stanikzai, Said Elias, Rajesh Rupakhety
Seismic Response Mitigation Of Base-Isolated Buildings, Mohammad Hamayoun Stanikzai, Said Elias, Rajesh Rupakhety
Civil & Environmental Engineering Faculty Publications
Earthquake response mitigation of a base-isolated (BI) building equipped with (i) a single tuned mass damper at the top of the building, (ii) multiple tuned mass dampers (MTMDs) at the top of the building, and (iii) MTMDs distributed on different floors of the building (d-MTMDs) is studied. The shear-type buildings are modeled by considering only one lateral degree of freedom (DOF) at the floor level. Numerical approach of Newmark's integration is adopted for solving the coupled, governing differential equations of motion of 5- and 10-story BI buildings with and without TMD schemes. A set of 40 earthquake ground motions, scaled …
