Using the component method introduced in Eurocode3 and Eurocode4, and aiming at the existing methodical shortage of end-plate beam-column composite joint initial rotational stiffness analysis, we proposed a detailed calculating procedure for the end-plate beam-column composite joint under hogging moment. Considering the influence of different location of longitudinal reinforcement and shear stud and that of stiffness of column web, a component model for initial rotational stiffness analysis was presented. The analytic result was compared with that of experiment. The result indicates that this ...
