چکیده مقاله:

This paper presents an assessment on a friction-slip connection for moment frames with continuous beams based on the existing detail and proposed a new configuration for rigid connections in moment frames with continuous beams, which is also capable of being developed as a friction-slip connection.In conventional moment frames, beams are placed between two adjacent columns connecting to the column flange faces; but in moment frames with continuous beams, two beams are continuously passed next to the column. The current practice for rigid connections in moment frames with continuous beams is based on the detail which is presented in [1]. In this detail; two vertical plates, R Plates, are placed on column flanges, and the beams are connecting to these plates via their wings. In the mentioned detail, it was assumed that the load transfers with in-plane action between RPL and column; but the results showed that the out of plane action of RPLs could be significant. Although this action provides extra capacity in rigid connections, it is not pleasant in friction connections due to changing the pretension load of bolts.A new configuration is proposed in this paper as an alternative to this detail, which can also be used as a friction-slip connection and provides a friction connection in moment frames with continuous beams. So instead of the plastic behavior of structural elements, these friction joints can be used as an energy-dissipating system
