Composite beam–to-column joints significantly influence the global stiffness, strength, and force redistribution capacity of steel–concrete composite frames. Although the Eurocode component method provides a rational basis for characterization joint, its manual application remains time-consuming and error-prone, which limits its systematic use in design and parametric assessment. This study applies the Eurocode 3/Eurocode 4 component method to composite beam–column joints with a non-extended end plate, and develops a dedicated calculation program to evaluate the joint design moment resistance ( ) and initial rotational stiffness ( ) and to support parametric studies. The parametric results show that increasing the slab longitudinal reinforcement ratio can raise ( ) by up to 27.53% (limited end-plate configuration) and increase ( ) by up to 122.416% (non-extended end plate configuration). Increasing the beam section height enhances ( ) by up to 83.068%, while the stiffness advantage of the flush end plate over the limited end plate can reach 110.944%. The end-plate thickness exhibits a saturation effect: beyond a threshold thickness close to flange thickness of profile tfc, further increases provide negligible gains in ( ) and ( ). These findings provide practical guidance for optimizing joint detailing and avoiding unnecessary over-dimensioning, while the developed software enables rapid Eurocode-consistent evaluation of composite joint performance.
