چکیده:
To reduce dynamic response of a semi-rigid frame with bolted connections, energy dissipation materials may be placed at a connection between the end plate and column flange or between the angle and member flange. In this article a three-span three bay frame with semi-rigid connections having three different capacities and energy dissipation materials analytically modeled by idealizing semi-rigid connection and energy dissipation materials as rotational spring and damper, respectively. The numerical model included nonlinear connection behavior, member yielding and geometrical nonlinearity of the structure. The pushover and dynamic analyses of the frames were performed using OPENSEES analysis program and dynamic analyses of frames with and without connection dampers show that there is an optimal damper damping coefficient by which the seismic responses of semi-rigid frame, including lateral displacements can be significantly reduced.
