Abstract: Horizontal cracks occur at the web of prestressed bridge girder ends during prestress release due to the spalling force, which is produced by the transfer of the prestressing force to the concrete. To avoid using a ...

Abstract: Horizontal web cracks are frequently observed at the ends of pretensioned concrete members (I girders or Bulb Tee girders) at the time of prestress transfer. Using a modified Gergely–Sozen (mG-S) model to calculate the ...

Abstract: Fiber reinforced concrete (FRC) has been gradually applied to the construction of precast segmental bridges, but due to the discontinuity of the joint structure and the existence of keys, the stress at the joint is complex. ...

Abstract: Segmental prestressed-concrete box girders (SPCBGs) with external unbonded and internal bonded posttensioning tendons have been widely used in the construction of bridge structures. These SPCBG bridges have many attractive ...

Abstract: In 2008, 77 prestressed concrete adjacent box girder (PCABG) bridges were selected and inspected to determine their typical defects and document their performance. Longitudinal cracking in the web of many beams was documented ...

Abstract: Epoxy resin joints for precast concrete segmental bridges protect internal posttensioned tendons from corrosion, compensate for irregularities between joint interfaces, and act as a joint lubricant. The shear strength, ...
