Development, Testing, and Analysis of a Rotational Friction Connection for Improving the Seismic Performance of Metal Building Systems with Hard Walls
(2018-07-27)
The use of metal building systems has become commonplace in today’s society. For well over two decades, the performance of metal building systems during seismic events has been the subject of intense research. It was ...
Performance Evaluations of Sediment Barrier Practices and Unmanned Aircraft System Mapping Technologies
(2018-11-15)
Sediment barriers are sediment control practices typically installed along the perimeter of construction sites that are intended to intercept, capture, and temporarily contain sheet to shallow concentrated flows prior to ...
Evaluation of HDPE and PVC Pipes Used for Cross-drains in Highway Construction
(2011-04-06)
The Federal Highway Administration (FHWA) passed regulations mandating that equal consideration be given to the specification of plastic pipe materials if they were judged to be equally acceptable on the basis of engineering ...
Laboratory Testing of Transverse Joints in Precast-Panel Bridge-Deck Replacement Systems
(2017-08-17)
Out of the 614,387 bridges in the United States, 56,007 are structurally deficient (FHWA 2016). In many instances this structural deficiency relates to the deck of the bridge. Deck degradation is very common in bridges ...
Investigation of Deep Foundations at the Spring Villa National Geotechnical Experimentation Site
(2018-04-27)
The Spring Villa test site is a National Geotechnical Experimentation Site located near Opelika, Alabama and managed by Auburn University. The test site is located at the southern end of the Piedmont geologic province and ...
Use of Anova Asphalt Rejuvenator and Balanced Mix Design Principle to Improve the Performance of High-RAP Asphalt Mixtures
(2019-10-22)
The use of recycled materials like Reclaimed Asphalt Pavement (RAP) in asphalt mixtures is now a common practice with associated economic, social, and environmental benefits. However, asphalt mixture performance issues, ...
A New Concept Design of Directional Rumble Strips for Deterring Wrong-way Freeway Entries
(2016-05-03)
Wrong-way driving (WWD) on freeways has been identified as a serious traffic safety problem. Drivers who make wrong-way entries onto freeways pose a serious risk to the safety of other motorists and themselves. This study ...
Field Evaluation of Near-Surface Mounted, Fiber-Reinforced Polymer Strips for Strengthening of a Continuous Reinforced Concrete Bridge
(2016-04-27)
The Letohatchee bridge is a continuous, reinforced concrete, deck-girder bridge maintained by the Alabama Department of Transportation (ALDOT) along AL 97 over I-65 near Letohatchee, Alabama. The bridge is deficient in ...
The Application of Self-Consolidating Concrete (SCC) in Full Scale Drilled Shafts
(2010-08-09)
Drilled shafts are being built larger and deeper, and this has increased the challenge in creating quality drilled shafts. Due to longer placement times and more required reinforcement, problems have been discovered with ...
Comparison of the reliability index between American codes and Chinese codes
(2018-11-15)
Abstract
The primary purpose of this research is to apply the reliability analysis techniques to the evaluation of two different series’ structural design codes using in America and China. This research is focused on ...
