Abstract

Addressing concerns such as excessive displacement and inadequate self-resetting capabilities in bearings for isolated bridges employing traditional double friction pendulum bearings, a new type of iron-based shape memory alloy-double concave variable friction pendulum bearing (Fe-SMA-DVFPB) was developed utilizing both the variable friction mechanism and the superelastic characteristics of shape memory alloy. Its constitutive model is constructed and its equivalent analysis model is determined. The displacement-based seismic design method of isolated bridges employing Fe-SMA-DVFPB is proposed. Drawing from practical engineering insights, isolation bridges are individually designed with various types of bearings, facilitating a comparative and analytical examination of their seismic performance. The research findings indicate that, in comparison to isolated bridges equipped with traditional double friction pendulum bearings, those utilizing Fe-SMA-DVFPBs demonstrate a notable improvement, with a maximum reduction in the relative displacement of bearings and residual displacement by 23.79% and 93.56%, respectively. The application of Fe-SMA-DVFPB isolation bearings effectively enhances control over both relative displacement and residual displacement. The decrease in relative displacement and residual displacement of the bearings in the isolated bridge significantly exceeds the increase in bending moment and shear at the pier bottom. The implementation of Fe-SMA-DVFPB can enhance the post-earthquake resilience of bridges.
