Abstract

The invention discloses a sliding-friction pendulum combined shock-insulation layer with an ultra-large bottom surface. The combined shock-insulation layer comprises an upper spherical shell layer, a lower spherical shell layer and sliding frames. Four arc-shaped spherical faces are arranged on the upper surfaces of the lower spherical shell layer. Four arc-shaped spherical faces are arranged on the lower surface of the upper spherical shell layer. Each sliding frame is composed of a plurality of sliding blocks, upper connecting components, lower connecting components, connecting beams and sliding frame columns, wherein the sliding frame columns are connected between the upper connecting components and the lower connecting components, and the lateral portions of the upper connecting components and the lateral portions of the lower connecting components are connected with the connecting beams. The upper end surfaces of the upper connecting components and the lower end surfaces of the lower connecting components are welded to the sliding blocks. The sliding frames are in overlap joint with the arc-shaped spherical faces of the upper spherical shell layer and the arc-shaped spherical faces of the lower spherical shell layer through the sliding blocks. According to the sliding-friction pendulum combined shock-insulation layer with the ultra-large bottom surface, the sliding frames are formed through connection of the sliding blocks, and the integral shock-insulation layer is formed by the sliding frames, the upper spherical shell layer and the lower spherical shell layer; and the span of the shock-insulation layer is quite large, the allowable deformation, in the horizontal direction, of the shock-insulation layer is far larger than that of a shock-insulation support, and the requirement for horizontal deformation of the shock-insulation layer under an extremely-powerful earthquake can be completely met.

Description

technical field [0001] The invention belongs to the technical field of shock absorption and isolation of building structures, and relates to a combined shock isolation layer of a sliding friction pendulum with a super large bottom surface. Background technique [0002] Seismic isolation technology is an outstanding research achievement in the field of structural seismicity in the past 50 years, and has been widely used in my country. Seismic isolation measures can make the superstructure in an elastic or weakly nonlinear state under the action of a large earthquake, reducing the seismic response of the superstructure. However, due to its clear failure mode, the deformation of the isolation layer and the overturning of the overall structure are prominent problems of the isolation structure under the action of a super large earthquake. Common seismic isolation devices for building structures include rubber bearings and friction pendulum bearings, whose horizontal deformation ...
