Effect Of Transverse Post-Tensioning On Moment Distribution Between Channel Girders, William Eubanks
Effect Of Transverse Post-Tensioning On Moment Distribution Between Channel Girders, William Eubanks
All Theses
This thesis investigates the strength of prestressed concrete channel girders used
in bridges in South Carolina and how to improve their load distribution. The specimens
are 30 feet in length, 33 inches wide and 17 inches deep. South Carolina has 377 bridges
containing prestressed concrete channel girders and many of these bridges received a
poor load rating in a recent load rating project conducted by the South Carolina
Department of Transportation (SCDOT). The research included flexural testing of seven
individual channel girders and load distribution tests of three transversely post-tensioned
channel girders. Individual flexural testing was done to determine the …
The Feasibility Of Using High Strength Stainless Steel In Pre-Stressing Applications, Rana Khaled Morsy
The Feasibility Of Using High Strength Stainless Steel In Pre-Stressing Applications, Rana Khaled Morsy
Theses and Dissertations
This paper evaluates the applicability of using a corrosion-resistant reinforcement high strength stainless steel strands (HSSS) Duplex 2205 in pre-stressing applications. HSSS-Duplex 2205 is a high performance steel which can be used as an alternative to the conventional carbon steel strands, for a better service life. The high strength and corrosion resistance of the material allows it to show its impressive performance in marine structural applications. Although the use of HSSS-Duplex 2205 could be initially costly; however, the improved durability and extended service life of the concrete structures using HSSS would require less life-cycle cost. Although there is a gap …
