Web12 dec. 2024 · Prestressing concrete bridges involves casting concrete beams with longitudinal holes for steel tendons—cables or bars—like reinforced concrete, but the holes for the tendons are curved upward from end to end, and the tendons, once fitted inside, are stretched and then anchored at the ends. Web12 apr. 2024 · In the context of a single-tower cable-stayed bridge, the effects of the ambient temperature change, stiffness degradation of the main beam and cable damage on the deflection of the main girder under the action of self-weight are investigated. To explore the possibility of identifying cable damage based on the deflection of the main girder, the …
