Connection Demand Prediction for the Design of Precast Concrete Wall Panels Subjected to Blast Loads
(2015-01-09)
One challenge in design of structures for highly impulsive loading is accurately predicting the peak transient shear and the corresponding connection force demand at supports. Single-degree-of-freedom (SDOF) approaches ...
Target Reliability Analysis for Structures
(2015-01-06)
Structural performance depends on load and resistance parameters, in particular magnitude and frequency of load components and their combinations, strength of materials, modulus of elasticity, dimensions, rate of deterioration, ...
Exploration of Crash Severity and Location in Work Zone-Related Crashes in Alabama
(2015-01-07)
Work zones are necessary for maintenance and improvement of highways, but they also present opportunities for crashes that might not occur under normal driving conditions. From 2006-2011, 3,192 crashes resulted in some ...
Measuring and modeling the impact of roadway runoff on a headwater tributary of the Cahaba River
(2015-07-24)
Stormwater runoff from highways has been a relevant focus of study both in terms of its characterization during construction phases as well as during the operational years. Highways have been thought to have adverse impacts ...
A Review of the Alabama Department of Transportation’s Policies and Procedures for Life-Cycle Cost Analysis for Pavement Type Selection
(2015-05-11)
This thesis examines the process of life-cycle cost analysis for pavement type selection and gives specific consideration to the policies and procedures used by the Alabama Department of Transportation as of June 2013. ...
Evaluation of Driver Assistive Truck Platooning on Traffic Flow
(2015-07-21)
Interest in driver assistive truck platooning (DATP) through the application of coordinated adaptive cruise control in the freight trucking industry is on the rise due to its expected benefits on the roadway. To investigate ...
Development, Experimentation, and Implementation of a Gap Damper System to Limit Displacements in Extreme Ground Motions
(2015-05-05)
Studies have shown the effectiveness of providing supplemental energy dissipation in base-isolated structures to reduce displacements at the isolation level, often with consequences to superstructure performance. A previous ...
A Study of the Effects of Pavement Widening, Rumble Strips, and Rumble Stripes on Rural Highways in Alabama
(2015-05-05)
Run-off-road (ROR) crashes are usually severe and account for a significant amount of highway
fatalities. It is estimated that more than 50% of the fatal crashes in the United States and in
Alabama are ROR crashes. Rural ...
Evaluation of AIMS-II and Micro-Deval for Friction Characteristics of Aggregates
(2015-05-08)
There is a need for a rapid quantitative way to evaluate the quality of aggregate friction properties for use in an asphalt surface (wearing) course. Aggregates that are resistant to polishing and capable of retaining their ...
Earthquake Induced Inelastic Demands on Buckling Restrained Braces
(2015-07-29)
Buckling restrained braces (BRBs) show an increasing popularity in modern designs due to their high ductility capacity over conventional braces. Non-linear tests on isolated BRBs have shown the symmetrical hysteresis ...
