A beam-to-column connection with visco-elastic and hysteretic dampers for seismic damage control
https://orcid.org/0000-0003-0687-0069
Abstract A new steel beam-to-column connection for seismic energy dissipation is presented in this paper. Dissipation of energy is provided for with the use of visco-elastic material that works in shear and of elasto-plastic steel bolts that act in bending. Through both analysis and cyclic tests, it is shown that the proposed connection produces stable hysteretic cycles superior to the conventional connections. This is while the structural members and connectors including beam, column, connection plates, welds and bolts do not experience any damage even at story drifts corresponding to large earthquakes. Installation and repair of the proposed detail are easy to implement as it consists of placing a visco-elastic damper as a lower pad on the seat angle of the connection and a series of bolts connecting the top flange to the seat angle. Effects of various parameters on the behavior of the proposed connection are studied comprehensively.
