A total of five tests on biaxially loaded column specimens were conducted to investigate the complete behavior of load-deformation characteristics from zero load until failure. The specimens were tested under horizontal position with 60 ton hydrolic jack. Pin end was used for both ends to obtain higher accuracy of plotting curves.

Two specimens were tested with dial gages to obtain load-deflection curves and the other three specimens were tested with demec and strain gages to obtain load strain and moment-curvature curves. The strain gages were measured by weston bridge and deme-gages were measured by mechanical dial gage.

The above moment-curvature curves can be incorporated in several special purpose computer programs, which calculate the moment rotation and the load-deflection relationships for L-Shaped reinforced concrete columns under combined biaxial bending and axial compression. Calculated results were compared with the theoretical results from computer program and satisfactory agreement was obtained.
