Seismic Response Reduction of Steel MRF Using SMA Equipped Innovated Low-damage Column Foundation Connection
Abstract: Connections in MRFs
are the most important members and seismic behaviour is affected by function of
beam column connections as well as column foundation connections. If the
connections are able to provide the required ductility and efficiency against
the seismic excitation, the seismic capacity of the MRF performed by these
connections will be affected. SMAs have recently been used as a tool to
dissipate energy in structures. So far, using of them for column foundation
connections has been applied much less. In this paper, SMAs have been
introduced and an innovated column foundation connection equipped with SMA has
been suggested. Micro and macro behaviour of the connection has been studied
and it was applied in sample MRF. Seismic response of the MRF under different
earthquakes by equipping the connection with steels/SMAs bars have been studied
and compared. Finally, results indicated that MRF with this connection showed
proper seismic performance.
