High-Strength Concrete Columns in High-Rise Buildings

Strength and ductility of high-strength concrete columns were investigated by examining available test data. The results are summarized in terms of load and ductility capacities of columns. Experimental observations indicate that strength and ductility of high-strength concrete columns can be improved to levels that are usually expected of normal-strength concrete columns, provided that the core concrete is adequately confined by transverse reinforcement.
