Intelligent bi-directional self-resetting friction pendulum support

Abstract

The invention relates to an intelligent bi-directional self-resetting friction pendulum support which comprises a bi-directional self-resetting friction pendulum support body and an intelligent sensing system. The bi-directional self-resetting friction pendulum support body comprises an upper support plate, a lower support plate and a support main body, a first stainless steel plate and a second stainless steel plate are arranged on the inner wall of the upper support plate and the lower support plate, first sliding grooves are formed in two sides of the upper support plate, second sliding grooves are formed in two sides of the lower support plate, and a first plane sliding plate, a spherical cap plate, a spherical surface sliding plate, the support main body and a second plane sliding plate are sequentially arranged between the first stainless steel plate and the second stainless steel plate from top to bottom and can slide forwards, backwards, leftwards and rightwards relative to thetwo first sliding grooves and the two second sliding grooves. By the aid of the structure, the support has the advantages that horizontal deformation capacity is high, and the safety of a building structure can be effectively protected.

Description

technical field [0001] The invention belongs to the technical field of seismic isolation of civil engineering structures, and in particular relates to an intelligent two-way self-resetting friction pendulum support. Background technique [0002] The support is an important node component used to connect the upper structure (such as the main body of the building, etc.) and the lower structure (such as the foundation, etc.) in the building structure and bridge structure. The constraints should be as small as possible, and it should be easy to install, maintain and repair. [0003] Existing actual earthquake damage shows that the failure of nodal supports is one of the most common failure forms that lead to the failure of building structures or superstructures of bridge structures. At the same time, during the daily use of the structure, structural damage and collapse events caused by the quality problems of the bearing itself also occur from time to time. Once the support as...

Problems solved by technology

However, the thin-film pressure sensor can only detect the changes in physical and mechanical properties of the arc-shaped surface of the hinged slider, and cannot fully reflect the self-resetting ability and mechanical properties of the support.

Moreover, every time processing, the thin-film pressure sensor needs to be installed separately, which is inconvenient to install.

In addition, the lower hinged slider can only slide left and right relative to the lower support plate and the upper support plate, so the range of horizontal deformation capacity is small
