Investigation of Field Corrosion Performance and Bond/Development Length of Galvanized Reinforcing Steel, Tech Transfer Summary.

摘要

The primary objectives of this study were to investigate the difference in bond strength and development length between galvanized reinforcing steel and epoxy-coated bars by means of beam end tests and to instrument a bridge with sensors to evaluate, over long periods of time, the field performance of the galvanized reinforcing steel used in the bridge. This study was not intended to define a new design method or an independent relationship for each specimen tested. It was intended to compare, in a relative manner, the bond strength of concrete-to-galvanized reinforcing steel to concrete-to-epoxy-coated bars.
