A Comparative Study on Seismic Assessment of Building Using SMA in Base Isolation and Beam Column Joints
Abstract: The seismic design of the moment-resistant plastic frames is aimed at forcing the structure to respond to the strong action of the weak beam, in which plastic loops are expected to form into beams on the faces of the columns. The regions of the khang are described in detail in such a way that the output of longitudinal steel bars allows to dissipate the energy of the earthquake. If SE SMA is used as a reinforcement instead of steel in the right places of the hinges or in the basic insulation, it will not only be able to dissipate adequate seismic energy, but also restore its original shape after the seismic event. Due to the higher cost compared to the cost of other building materials, SMA longitudinal ribs can be used together with steel ribs in the articulated areas of the beams. Such BCJs can allow design engineers to design connections that show minor damage and mitigate joint repairs after an earthquake. Keywords: Seismic, base isolation, SMA, beam, column & joints
