Friction pendulum connected fabricated steel structure system and design method thereof

Abstract

The invention discloses a friction pendulum connected fabricated steel structure system and a design method thereof. The friction pendulum connected fabricated steel structure system comprises at least two layers of steel frame structures and a group of friction pendulum shock isolation devices; steel columns of each layer of steel frame structure are disconnected at the joint with the lower floor; the friction pendulum shock isolation devices are correspondingly arranged between the steel columns of every two layers of steel frame structures; each friction pendulum shock isolation device comprises an upper connection plate and a lower connection plate; the middles of the bottom surfaces of the upper connection plates are connected with plugging blocks; the bottom surfaces of the pluggingblocks are convex curved surfaces which are convex downwards; lugs are arranged on the top surfaces of the lower connection plates; plugging slots are formed in the tops of the lugs; the bottom surfaces of the plugging slots are concave curved surfaces which are concave downwards; the plugging blocks are correspondingly plugged in the plugging slots; the tops of the plugging blocks are higher thanthe tops of the plugging slots; and distances are reserved between the side walls of the plugging blocks and the side walls of the plugging slots. The friction pendulum connected fabricated steel structure system is capable of solving the technical problems that the existing fabricated steel structure buildings are complicated in connection joints, large in field workload and low in constructionefficiency, the joints of the frame structures are rigidly connected and the seismic resistance of the frames is relatively bad are solved.

Description

technical field [0001] The invention relates to the technical field of architectural engineering structure design, in particular to an assembled steel structure system connected by friction pendulum and a design method thereof. Background technique [0002] Prefabricated steel structure buildings have become a main theme of architectural development because of their own green design and architectural concepts, high construction efficiency, low environmental pollution, detachable, recyclable and easy maintenance and many other advantages. [0003] Most of the current assembled steel structure buildings are connected by bolts or welds, and most of them follow the principle of "broken beams without continuous columns, broken secondary beams with continuous main beams". The on-site connection of multiple nodes reduces the construction efficiency to a certain extent. Moreover, the connection nodes are all rigid connections, and most of the shock absorption is realized through the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a prefabricated steel structure system connected by friction pendulum and its design method. It is necessary to solve the problem of complex connection nodes of existing prefabricated steel structure buildings, large on-site workload, low construction efficiency, and the joints of frame structures. It is a technical problem that the seismic performance of the frame is relatively poor due to the rigid connection
