Traffic impact assessment and mitigation strategies for disruptions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation research focuses on modeling traffic conditions affected by disruptive events such as work zones, incidents, and hurricanes. Using a ...
Approaches for comparing the structural characteristics of different representations of transportation systems
(University of Missouri--Columbia, 2018)
vertices in Net A and assigned arcs in Net B grouped into two distance groups (<=10m, and > 10m). 97.5% of the assigned arcs in Net B are within 10 meters of Net A path vertices, and only 2.5% are beyond this distance. Similar observation occurred when...
Calculated versus measured static capacity for two pile types
(University of Missouri--Columbia, 2018)
The Missouri Department of Transportation decided to replace two bridges in northeast New Madrid Country, Missouri. The bridges were in service for approximately 50 years and both were founded on driven piles. The bridge ...
Statistical and simulation methods for evaluating stationary and mobile work zone impacts
(University of Missouri--Columbia, 2018)
In 2014, nearly 10% of overall congestion on freeways was due to the presence of work zones (WZs), equivalent to 310 million gallons of fuel loss (FHWA, 2017a). In terms of safety, in the US, every 5.4 minutes, a WZ related crash occurred in 2015...
Analysis and design of reinforced concrete wall systems for blast
(University of Missouri--Columbia, 2018)
/prestressed concrete and insulated tilt-up concrete sandwich panels for exterior walls is common practice. These forms of construction provide a thermally efficient and high-mass wall that enhances the energy efficiency and blast resistance of the building making...
Fatigue crack strengthening using pre-stressed composite patch
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The fatigue life of steel bridges can be extended by externally bonding carbon fiber reinforced polymer (CFRP) patches to the damaged elements arrest ...
Load and resistance factor design of drilled shafts subjected to lateral loading at service limit state
(University of Missouri--Columbia, 2018)
, there are no guidelines implementing LRFD techniques for design of drilled shaft subjected to lateral loads using reliability-based analysis. On a national level, the AASHTO LRFD Bridge Design Specifications (AASHTO, 2012) specify that a resistance factor of 1.0 be used...
