Abstract:
Restrainer-type sliding bearing (RTSB) is a practical seismic isolation system for reducing the excessive displacement of flat sliding bearings under strong earthquakes to ensure the seismic safety of highway bridges. Due to the good corrosion resistance and considerable energy dissipation capability, SMA cables can be used in the RTSB to form the SMA-restrained RTSB to improve its performance. To realize the reliable seismic design of the SMA-restrained RTSB, this paper adopted the seismic resilience-based evaluation method to give the optimum design to minimize the seismic resilience of the bridge system.
