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 cyclically varying axial loads. This report documents the experiments and measured data and presents comparisons between measured and calculated responses.
