چکیده
To make the bearing capacity tests safer and more affordable for prestressed high-strength concrete (PHC) piles, this paper proposes a reaction device anchor piles filled with core grout based on geometric mechanical characteristics of PHC piles. The proposed has advantages convenient construction, strong controllability connection quality low cost. In addition, pile will not experience prestress unloading or tensile stress under effect upward pulling load. promote application developed tests, experimental studies are conducted bonding performance between inner wall pile. influence various factors such as strength grout, grouting length, curing time, diameter bond investigated. Results show that increases, decreases maximum difference 5%. length gradually stabilizes, no than 10% minimum values. higher is, greater is. increases increase time within 28 days curing, at 3 meets requirements test.

متن کاملCorrosion Performance of Concrete Cylinder Piles
Concrete cylinder piles produced by a centrifugally cast, vibrated, roller-compacted process have shown promising corrosion resistance in marine environments. Three bridges in the Florida panhandle with ~40 years in aggressive marine service and one newly constructed marine bridge utilizing concrete cylinder piles were examined. Examination of the older marine bridges showed minimal corrosion d...
متن کاملDuctility of Prestressed and Partially Prestressed Concrete Beam Sections
D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...
