Non-linear behaviour of one-bay steel frames with semi-rigid connections

This project studies the static non-linear behaviour of plane steel frames with semi-rigid connections. To describe the non-linear behaviour of the semi-rigid connections, the three-parameter power M-fr model is used. ANSYS software package is used for the non-linear analysis of the frames. Finite e...
