Description

technical field [0001] The invention relates to a shock-isolation layer, in particular to a friction pendulum array shock-isolation layer with integrally consistent curvature of a chute, which belongs to the construction field. Background technique [0002] At present, large-span structures such as space structures mostly use rubber bearings or lead rubber bearings when considering seismic isolation. These bearings have a better effect on the horizontal vibration isolation of the structure, but they are not suitable for structures with obvious vertical vibrations. Large-span structures; large-span structures have huge volume and quality, and the existing three-dimensional seismic isolation bearings generally have insufficient vertical bearing capacity; Friction pendulum bearings with high bearing capacity requirements are a better choice for large-span structure isolation. The friction pendulum support was first proposed by Zayas et al. of the University of California, Berk...
