Experimental Study of Reinforced Concrete Columns Subjected to Multi-Axial Cyclic Loading
Five nominally identical quarter-scale reinforced concrete columns were constructed and tested using multiaxial cyclic loading histories. The columns were detailed to satisfy requirements of current North American building codes for reinforced concrete structures in regions of high seismic risk. The columns were loaded as cantilevers attached to stiff foundation blocks. The primary variable was the load history. Load histories included (1) uniaxial cyclic lateral loads with constant axial load, (2) biaxial cyclic lateral loads with constant axial load, and (3) biaxial cyclic lateral loads with cyclicly-varying axial loads. Measured responses indicate that inelastic deformations in these tests were due primarily to effects of flexure and reinforcement slip from the foundation blocks. Visible damage, stiffness, and resistance were markedly affected by the load history. Existing procedures for computing stiffness and strength under biaxial loading correlated reasonably well with the measured behavior.
