Seismic Assessment of the Steel Moment Resisting Frame Equipped With Friction Beam-to-Column Joints

Abstract

Enhancing the seismic response of structures with supplementary dissipative devices is an effective design strategy. A possible low-cost and easy to maintain solution to optimize the seismic performance of steel Moment Resisting Frames is inserting friction devices into beam-column joints. The applicability of such a system will be demonstrated by building a real-scale structures in the campus of the University of Salerno. The present paper aims to evaluate the seismic behavior of the prototype building using the framework of performancebased earthquake engineering method at different performance levels. To this end, nonlinear dynamic analyses are carried out on a three-dimensional (3-D) models of the prototype developed in "OpenSees". The results show that this type of structure can be free of damage under earth-quakes corresponding to the design and maximum considerable levels.
