Numerical and Experimental Studies on Cyclic Behavior of Beam-to-Column Connection with Yielding Steel Damper

In this paper, cyclic behavior of a new type of beam-to-column connection comprising yielding damper with a circular pattern at depth of the beam was evaluated. The effects of different parameters on proposed connection behavior were also studied. Results of both finite element analysis and experimental tests showed that all the specimens of proposed connection have a stable cyclic behavior. Reliable design for damper at connection maintaining stiffness, strength, and energy dissipation in beam-to-column connections at an acceptable level concentrated inelastic deformations in damper, and also keeping structural members such as beams and columns in elastic range.
