Abstract
A total of four slender high strength steel fiber ( 20 vol. hooked ends 1 in and 2 in ) reinforced concrete columns were casted, cured and tested to failure under biaxially eccentric load us—KT MTS testing system. The experimental load-deflection behavior exhibits not only the ascending branch but also the descending branch of the load and deformation curves.
The experimental ultimate load capacity was analyzed by the equation of Failure Surface Method developed by Hsu. recently, the result shows that the analysis method is able to predict the ultimate load value for biaxially loaded slender concrete columns.
For biaxially loaded slender high strength columns with and without steel fibers, the comparative results of load-deflection behavior show not much difference in achieving the ultimate load capacity; however the columns with steel fibers develop hair line crack at the higher loads and spall off at the larger deformation as compared with the columns without steel fibers in them.
