This paper investigates the structural performance of Stalite lightweight self-consolidating concrete (LWSCC) beam-column joints under quasi-static reversed cyclic loading. Six beam-column joints made with different lightweight aggregate types (Stalite lightweight coarse [LC] and fine [LF] aggregates) and designed with/without joint shear reinforcement were cast and tested. The performance of tested specimens was assessed in terms of failure mode, hysteretic response, deformation, strength degradation, ductility, brittleness index, and energy dissipation capacity. The applicability and accuracy of design code provision in predicting the shear and flexural strengths of the tested joints were also investigated. The results indicated that it is possible to design Stalite LWSCC mixtures with a density ranging from 1888–1966 kg/m3, having a sufficient structural performance under cyclic loading. Properly designed LWSCC beam-column joints made with Stalite aggregates slightly reduced the load-carrying capacity by around 8.5% and ductility and dissipated energy by around 11.4% and 15.8%, respectively, compared to the normal-weight SCC (NWSCC) specimen. Despite the brittle nature of Stalite lightweight aggregates, LWSCC joints with sufficient hoops exhibited satisfactory cyclic performance and experienced ductile flexural beam failure. The results also indicated that LWSCC specimens containing Stalite fine aggregates showed better structural performance in terms of load-carrying capacity, strength degradation, ductility, brittleness index, and energy dissipation capacity compared to counterpart specimens made with Stalite coarse aggregates.
