Abstract

A high tension species of steel called“Hi-Strand”, for prestressed concrete was developed, and its mechanical properties and fatigue strength were studied.“Hi-Strand”, as its commercial name stands, has tensile strength about 20% higher than conventional PC steel called JIS PC strand.<br>In spite of this high tensile strength, it is proved that Hi-Strand has as much strength as JIS PC strand in many points. In this report (the first of three reports), its mechanical properties are discussed, and in succeeding reports its fatigue strength will be reported.
