Abstract

In the present study, experimental studies were performed on six reinforced concrete columns with non-seismic details under cyclic lateral loading. The major test parameters are axial load ratio, hook angle, longitudinal reinforcement ratio, and shear span to depth ratio. The structural performances and characteristics of the specimens were discussed in terms of hysteretic load-displacement relationship, maximum shear strength, drift capacity, damping ratio, and energy dissipation. In the test results, it was observed that axial load ratio significantly affected the maximum shear strength and drift capacity, while longitudinal reinforcement ratio and shear span to depth ratio affected the maximum shear strength only. Most of specimens were finally failed in flexure-shear mode caused by micro diagonal cracks at plastic hinge zone after yield of longitudinal tension reinforcement. When comparing the test results with the prediction of ASCE 41-06, it was found that ASCE 41-06 underestimated a plastic deformation of reinforced concrete columns with non-seismic details.
