Performance Implications Of Bicycle Specific Treatments At Signalized Intersections, Andrew Kading Apr 2016

Performance Implications Of Bicycle Specific Treatments At Signalized Intersections, Andrew Kading

Civil and Environmental Engineering Master's Project Reports

A rise in cycling nationwide has brought an increased awareness of bicycle specific safety concerns, particularly right-hook crashes at signalized intersections. There are several common and emerging signal timing strategies that are can be used to improve the safety and efficiency of traffic signals for people on bicycles, including the Leading Bicycle Intervals (LBI), Split LBI, and Exclusive Bicycle Phasing (EBP). The leading and split bicycle intervals provide a head start for bicycles in advance of concurrent and conflicting motor vehicle movements, typically about 3-5 seconds. The EBP provides an interval only when bicycles are moving. To examine the performance …


Behavior Of Concrete Beams With Corroded Reinforcement Retrofitted With Carbon Fiber Reinforced Polymer, Needa Marwan Lingga Jan 2016

Behavior Of Concrete Beams With Corroded Reinforcement Retrofitted With Carbon Fiber Reinforced Polymer, Needa Marwan Lingga

Civil and Environmental Engineering Master's Project Reports

Severe premature deterioration has been reported in a large number of reinforced concrete (RC) structures in corrosive environments. This research project focused on the behavior of beams that contained corroded steel and were retrofitted with CFRP. The steel in RC beams were assumed to be fully corroded, representing the most severe loss in steel cross-section. Unidirectional CFRP sheets were used to strengthen the deteriorated beams. The experimental program included testing five simply supported rectangular cross section concrete beams. All beams were approximately 1/3rd scale models, 4in. x 6in. cross sections, and 6ft. long. In three beams, the oiled steel …
