HIGH PERFORMANCE CONCRETE COLUMNS SUBJECTED TO SINGLE OR DOUBLE CURVATURE BENDING

摘要

This paper presents the test results of eighteen High Performance High Strength Concrete (HPHSC) columns subjected to either single or double curvature bending. Column specimens were tested for both equal and unequal load eccentricities at the ends. The columns with load eccentricities on the same side of the column axis bent in a single curvature mode and those with eccentricities on opposite sides of the axis bent in a double curvature mode. An analytical procedure to predict the behaviour and the strength of columns is also briefly described.
