Abstract

The invention relates to a structure for strengthening anti-seismic performance of a steel frame, in particular to an anti-seismic structure of an energy-consumption angle brace. The anti-seismic structure of an energy-consumption angle brace comprises a frame beam and a frame column, wherein the node position of the frame beam and the frame column is provided with an energy-consumption angle brace plate; and the contact surface between the energy-consumption angle brace plate and the frame beam as well as the contact surface between the energy-consumption angle brace plate and the frame column are respectively fixedly connected by a connecting plate. The anti-seismic structure of an energy-consumption angle brace is favorable for flexible arrangement of frame structure space and is favorable for the arrangement and construction of a filler wall. Under the condition of no seism or under the condition of quaking frequently, the energy-consumption angle brace can perform the action of a common angle brace to protect the node; under the action of seldom-occurred seism, when the beam and the column have great relative rotation, the energy-consumption plate of the energy-consumption angle brace can yield, energy can be continuously adsorbed and consumed by being continuously pulled and stressed to yield, and on the effects of supporting the beam and the column and protecting the node can be kept so as to protect the safety of the node, avoid node damage and reduce seismic damage.

Description

technical field [0001] The invention relates to a structure for enhancing the anti-seismic performance of a steel frame, in particular to an anti-seismic structure for energy-consuming corner braces. The utility model belongs to the technical field of multi-storey and high-rise building technology. Background technique [0002] At present, in the seismic design of multi-story frame structures, in order to ensure the safety of the overall structure, the design principle of "strong joints and weak members" is generally adopted to ensure that the beams, columns and other main anti-corrosion When lateral force members enter yield, the nodes connecting these members do not fail first. No matter how strong the structural member is, it will not be able to function once the joints are damaged. Following the design principle of "strong nodes and weak components", not only can the main lateral force-resisting components such as beams and columns be protected, but also the seismic ac...
