Detection of effective prestressing of 1860-grade strands based on the microporous method

Abstract Existing tensioning cable prestress ensures bridge safety. This work presents the micro-hole release technique, which accurately measures the effective prestress of strands in existing prestressed concrete bridges. The strand drilling model was produced in Solidworks and Abaqus. The effect...
