Abstract

Tests of 10 reinforced concrete column specimens subjected to reversals of lateral deflection and axial force have shown that variations in axial compression can influence strength, stiffness, and deformation capacity of reinforced concrete columns. Measured relations between moment and rotation or strain were asymmetrical even through cross sections were symmetrical about the axis of bending and deflections were equal for each direction of sway. The shape of hysteretic loop was influenced by the range of axial-force variation and the state of change of axial force with lateral deflection. Implications for design of symmetrical reinforced concrete frames are discussed in terms of measured behavior of test columns.
