Abstract

A new type of seismic isolation device, SMA spring-friction bearing (SFB) is developed and its application to lattice grid structures is investigated in this paper. First, a simplified restoring model is derived to simulate the hysteretic behavior of the SFB. Then, a SFB specimen is fabricated and tested using cyclic protocol to validate the model of such an isolator. Finally, the feasibility and the seismic control effect of the SFB in the lattice grid roof with substructure are evaluated by performing a set of nonlinear time history analyses. The numerical results indicate that the SFB is effective in controlling displacement, roof acceleration and base shear of the lattice grid structures.
