- Abstract
- A common deficiency in existing reinforced concrete (RC) columns built without considering seismic load is that the lap splices are often short, poorly confined, and located at the end region of columns. Assessment of seismic capacity of RC columns with lap splices have mostly been based on experimental tests under axial load and uniaxial bending. To investigate the effect of biaxial bending on the seismic performance of existing RC columns with deficient lap splices, two full-scale specimens were fabricated and tested under uniaxial or biaxial loading. Experimental findings revealed that biaxial loading had significant effects on the hysteretic behavior of RC columns with deficient lap splices.
