Abstract
A new type of SMA-rubber bearing with regular hexagon connecting plates for laminated rubber pads is designed. Moreover, the mechanical model of the bearing as well as the corresponding MATLAB computing program are developed and compared with the ordinary SMA-rubber bearing. Furthermore, the new bearing is applied to K8 single-layer reticulated shell to test its seismic response. The studies indicate that the new SMA-rubber bearings consume energy more efficiently. The seismic responses of reticulated shells can be effectively reduced by using the new SMA-rubber bearings. The study also indicates that the developed SMA-rubber bearing provides superior performance than ordinary rubber bearing.
