In this numerical study, the rigid behavior of prefabricated beam-column joints has been investigated. Due to the criticality of lateral loads in seismic zones, the ductility, strength, and energy absorption of prefabricated rigid joints are crucial. Lightweight concrete is a common material in prefabricated concrete structures because of its advantages, such as easy formwork and transportation, as well as quick execution. Therefore, this study investigates the effect of lightweight concrete on the flexural rigidity of prefabricated beam-column joints. Furthermore, this study evaluates other significant factors in prefabricated structures, including the integrity of the concrete-rebar connection and preventing rebar slippage. In this study, Abaqus software was employed to model lightweight concrete constructed from Leca (Light Expanded Clay Aggregate) and low strength grout. The present numerical study analyzes eight numerical models with the same geometry, but different materials and joints. In this set of models, two of them are without couplers, and the rest are pinned with couplers in a beam-column joint. This study concludes that the effect of lightweight concrete on the joint is negligible. Additionally, grout significantly affects the joint zone. By variation in the strength of grout in the joint zone, the ductility and strength of the structure are directly affected.
