Parametric Study of SMA-based Friction Pendulum System for Response Control of Bridges under Near-Fault Ground Motions
This article presents a sensitivity study on shape memory alloy (SMA)-based friction pendulum bearings (FPBs) for response control of a three-span continuous isolated bridge. The responses of the bridge isolated with SMA-based FPB system are compared with those of the bridge isolated with FPB system. The effectiveness of SMA-based FPB system for response control is investigated through a case study. Results show that the residual displacement and peak displacement can be effectively reduced without significantly increasing the base forces of the bridge piers. The SMA-based FPB system can provide reliable recentering and energy dissipation capabilities for bridges against near-fault earthquakes.
