Two full-scale super assemblage of interior beam-column joints with and without fuse bars were designed, constructed, analyzed, modeled and compared their performances under in-plane lateral cyclic loading. Based on experimental results, the interior joint with fuse bars performed better than without fuse bars in terms of structural damages, ultimate lateral strength capacity, elastic stiffness, secant stiffness, ductility and equivalent viscous damping. It was observed that the inte-rior beam-column joint with fuse bars performed better than without fuse bars in terms of visual observations such as cracks propagation, width of cracks, spalling of concrete and mode of failure. Furthermore, experimental hysteresis loops were also validated with modeled hysteresis loops using Pampanin RC beam-joint (IHYST = 44) and HYSTERES Program. The percentage difference between these two hysteresis loops lies between 2 and 20%, which is acceptable because only one specimen was conducted and analyzed. Therefore, it is recommended to use fuse bars for construction of the RC buildings under moderate seismic regions especially in Sabah, Malaysia. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.
