Performance-Based Seismic Design of Friction Pendulum Bridge
In order to realizes that the actual working state of bridges coincides with the seismic design model,through numerical analysis and model test of conventional friction pendulum bearings,it is revealed that the current working state of fixed friction pendulum and movable friction pendulum can not"synchronously swing".Ve-locity-locked variable curvature friction pendulum can reasonably control the different working modes of bear-ings under the normal use of bridges and different levels of earthquakes,achieve the performance-based seis-mic design objectives,effectively improve the seismic performance of bridges and save engineering costs.
