Abstract: This case study proposed and evaluated an approach to repair post-tensioned prestressed concrete bridge girders in cold regions. The girders had severe frost-heaving cracks and unhardened cementitious grout in the prestressing ...

Abstract: This study evaluated the fatigue performance of rib-to-deck welded joints in orthotropic steel decks (OSDs) with thickened edge U-ribs (TEUs). Fatigue performance of four rib-to-deck specimens with TEUs was investigated ...

Abstract: Compared with suspension bridges with a single main cable in each cable plane, adding a cable with a different sag may increase the vertical stiffness, but also increase the demand of frictional resistance at the saddles. ...

Abstract: The frictional resistance between main cable and saddle of a long-span, multispan suspension bridge is significant for the safety of the bridge. Typically, the main cable of a long-span, multispan suspension bridge has ...

Abstract: This paper investigates the viability and advantages of incorporating off-specification fly ash (OSFA) into the production of strain-hardening cementitious composites (SHCC). Influences of variables in mix design on key ...

Abstract: The capability to accurately evaluate the frictional resistance between the main cable and saddle is essential for the design and evaluation of suspension bridges. In this paper, an analytical model is developed to predict ...

Abstract: The perfobond rib (PBL) shear connector group composed of multiple layers of PBL shear connectors has been proven to be one of the most effective load-transferring components and is widely used in cable-stayed bridges. In ...

Abstract: This paper presents high temperature measurements using a Brillouin scattering-based fiber optic sensor and the application of the measured temperatures and building code recommended material parameters into enhanced ...
