Lattice column type n-shaped lateral-force-resistant supporting frame

Abstract

The invention provides a lattice column type n-shaped lateral-force-resistant supporting frame. The lattice column type n-shaped lateral-force-resistant supporting frame comprises vertical columns, cross beams and n-shaped supporting assemblies. The two vertical columns are arranged in parallel, the multiple cross beams are vertically arranged between the two vertical columns at equal intervals, and the position between the two vertical columns is divided into multiple rectangular frames. One n-shaped supporting assembly is fixedly arranged in each rectangular frame. The rigidity degenerationof the n-shaped mesh supporting structure is slow, seismic resistance and energy consumption can be better facilitated, the span of the frame is indirectly reduced through lattice columns formed by supports and frame columns, as supporting force is scattered into multiple rod parts, when a certain rod part is damaged, internal force is distributed again, the other rod parts can still provide the rigidity, the rigidity degeneration of the whole structure is slow, and the ductility is better. Meanwhile, the lattice column type n-shaped lateral-force-resistant supporting frame still has high rigidity and bearing capacity.

Description

technical field [0001] The invention belongs to the technical field of anti-lateral force support, in particular to a lattice column type door-shaped anti-lateral force support frame. Background technique [0002] Since the components of steel structure buildings can be factory-made and installed on site, the construction period can be greatly reduced, and the steel in steel structure buildings can be recycled, which can greatly reduce construction waste and be more environmentally friendly, so it is widely used in industrial buildings and in civil buildings. There is an urgent need for new technologies to support the design and construction of multi-tall buildings. [0003] For steel structures, as the height of high-rise and super-high-rise residential buildings increases, the influence of lateral load effects (including earthquake action and wind load, etc.) is prominent. capacity, the steel frame-bracing system is a commonly used system in multi-story steel structures....

AI Technical Summary

Problems solved by technology

[0004] In the existing steel structure buildings, in order to improve the lateral stiffness and lateral bearing capacity of the building, components such as large supports are usually used, and the ductility of the structure is poor, especially under the action of reciprocating horizontal earthquakes, when the force of the structure enters the elastic-plastic range , the shear capacity of the floor and the lateral stiffness of the structure drop sharply, and the lateral displacement between floors increases excessively, which eventually leads to the overall instability and failure of the structure.

[0005] The current anti-lateral force components affect the aesthetics of the building, are inconvenient to open doors and windows, affect the installation of the wall, and cannot be organically unified with the enclosure
