In one or two story low-rise buildings, generally, hoops have not been used in the beam-column joints due to lack of proper design codes and difficulty in construction. Further, such buildings show weak-column and strong-beam behavior under seismic loading because architecturally small size columns are preferred and relatively low axial loads are applied to the columns. In such conditions, beam-column joints and the overall structures are expected to be vulnerable to earthquake loading. Therefore, in this study, lightly reinforced concrete beam-column connections were studied. Cyclic loading tests were performed to evaluate the strength of beam-column joints. The test parameters were reinforcement ratio and details of joint hoops, and types of joints (i.e. exterior or interior joint). The test results showed that the shear strength of exterior joints was mainly affected by the joint hoop ratio and the development length of beam longitudinal reinforcement. The exterior joints with volumetric ratio of hoops higher than 0.58% successfully attained the joint shear strength specified in ASCE41-13. The interior joints, on the other hand, achieved joint shear strength 23~70% higher than the specified strength even without joint hoops.
