Abstract:
Results of Series 7 of the ACI column investigation arereported. This series included tests on the effect of amount and grade of spiral reinforcement on strength of columns. Within the range of the strains measured variation in the amount or grade of spiral had practilcally no effect on the deformation of the columns. For fast loading, the strength added by the spiral was about equal to the strength added by an equal amount of longitudinal reinforcement of the same yield-pointstress.
