Description

technical field [0001] The invention belongs to the technical field of bearing performance evaluation, and more specifically relates to a method for evaluating the performance of friction pendulum type seismic isolation bearings for bridges and buildings. Background technique [0002] As one of the most destructive sudden disasters, earthquakes can cause casualties and property losses, damage or even collapse of buildings and bridges. In many major earthquakes at home and abroad, the bridges and buildings that are the bottom line of life have been severely damaged. At the same time, roads have been interrupted, secondary disasters have been caused, and great difficulties have been brought to disaster relief and reconstruction work after the earthquake. Therefore, the research on engineering shock absorption and isolation technology is of great significance for protecting human life and property and reducing earthquake damage losses. [0003] The friction pendulum isolation ...
