Cyclic Behavior of Beam-to-Column Connection with Yielding Steel Rods Damper in Shear

Document Type : Original Article

Abstract
The present study tries to examine the seismic behavior of a new type of beam-column connection having yielding damper with circular placement pattern. The main purpose of the proposed system is to use yielding dampers in a space as high as the beam depth in order to occupy much lesser space, and not to reduce the useful height of the story  in the beam-column connection, so that the inelastic deformations from cyclic loading is restricted to the dampers. Three samples were made in the laboratory and were loaded up to 0.05 radian rotation under the cyclic loading. In order to evaluate the numerical modeling techniques and analyses in predicting the cyclic behavior of the proposed connections, finite element models of  laboratory samples were made and were analyzed based on corresponding  loading pattern. Based on the numerical and experimental results, inelastic deformations  were concentrated  in the dampers for all proposed connections and  the beam and the column remained within the elastic range. It is also possible to achieve a higher resistance that of the plastic moment of the beam in the proposed connection with a suitable design.
