Verifying Automated Prestressed Concrete Design Software For Mdot Bridge Design Standards, Hussein Kadhim Abood Khalaf
Verifying Automated Prestressed Concrete Design Software For Mdot Bridge Design Standards, Hussein Kadhim Abood Khalaf
Masters Theses
The design and analysis of bridges is a very critical and time consuming process. The automation of bridges design can save us time and effort, but the designer must have enough background with structural design of bridges in order to be able to analyze and understand the output of the automated design. This research shows the design and analysis of the superstructure of the US-27 Interchange Bridge at M-57 in Gratiot County of Washington Township, Michigan. The main purpose of this research is to establish a comprehensive design example following AAHTO LRFD Bridge Design Specifications and Michigan Bridge Design Manual. …
Evaluation Of The Use Of Painted And Unpainted Weathering Steel On Bridges, Theodore Hopwood Ii, Sudhir Palle, Bobby W. Meade, Rick Younce
Evaluation Of The Use Of Painted And Unpainted Weathering Steel On Bridges, Theodore Hopwood Ii, Sudhir Palle, Bobby W. Meade, Rick Younce
Kentucky Transportation Center Research Report
KTC researchers studied the use of unpainted weathering steel on bridges, using findings of inspections performed on Kentucky Transportation Cabinet (KYTC) bridges constructed with both painted and unpainted weathering steel as well as laboratory testing. Laboratory tests were conducted on test panels of conventional and weathering grades of steel to determine the performance of barrier and zinc-based coatings over abrasive-blasted substrates of those steel types in both the new and corroded conditions. The report provides the following recommendations for the use of painted and unpainted weathering steel on Kentucky bridges based upon both the field and laboratory findings:
- KYTC should …
Shear Behavior Of High-Strength Self-Consolidating Concrete In Nebraska University Bridge Girders, Alex Griffin, John J. Myers
Shear Behavior Of High-Strength Self-Consolidating Concrete In Nebraska University Bridge Girders, Alex Griffin, John J. Myers
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Current reinforced and prestressed concrete design equations were developed for conventional concrete elements. Self-consolidating concrete (SCC) typically contains a lower coarse aggregate content and size than conventional concrete, which potentially hinders the aggregate interlock contribution to a concrete's shear strength. Thus, shear design equations must be verified with SCC mixtures. Two full-scale precast, prestressed concrete Nebraska University girders were tested to assess the shear behavior of high-strength SCC. Both girders were designed to permit two tests on each girder, both with and without shear reinforcement. Ultimate shear loads and crack patterns were documented and compared with code estimates, finite element …
