For the failure mechanism of anchor cable lags behind practice demand for theoretical models, Abaqus technique was used to analyze anchoring performances grouted under conditions free and non-free rotating. The tension-torsion coupling characteristics progressive anchorage segment were studied during pull-out test. torsion response internal horizontal vertical strain changes in concrete also an...

Grouted post-tensioned (PTd) concrete systems are widely used in long-span segmental bridges with a target service life of 100+ years. However, the usage inadequate grout materials and grouting practices have resulted formation unwanted air voids duct, which turn led to premature corrosion (say, within about 20 years) strands failure tendons. Also, re-grouting/repairing void regions localized a...

In this study, two short precast concrete columns and two cast-in-situ concrete columns were tested under cyclic loads. It was shown that the sleeve grouted connection was equivalent to the cast-in-situ connections for short columns when the axial compression ratio was 0.6. In order to determine the influence of the axial compression ratio and the shear-span ratio on the shear capacity of the h...
