Abstract

The major sources of energy dissipation in steel frames with partially restrained (PR) connections are evaluated. Available experimental results are used to verify the mathematical model used in the study. The verified model is then used to quantify the energy dissipation in PR connections due to hysteretic behavior, due to the viscous damping and at plastic hinges if they are formed. Flow low damping values, the dissipation of energy at plastic hinges is comparable to that due to viscous damping, and increases as the frame approaches failure. The study confirms the general observations made in experimental investigations for steel frames with PR connections, however, proper consideration of the stiffness of PR connections and other dynamic behavior.
