Abstract

The invention relates to the technical field of earthquake-proof building structures and provides an X-shaped arranged anti-bending support structure and a connecting method thereof. The structure comprises a first anti-bending support component and two second anti-bending support components, wherein the two second anti-bending support components are respectively fixed with a middle joint of the first anti-bending support component, so that one first anti-bending support component and two second anti-bending support components are arranged in X shape. In the scheme, the two second anti-bending support components are respectively fixed with the middle joint of the first anti-bending support component, so that one first anti-bending support component and two second anti-bending support components are arranged in X shape and the structure has the advantages of high lateral rigidity, capability of saving construction space and post-earthquake resetting function.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of building components, in particular to an X-shaped arrangement of anti-buckling support structures and a connection method thereof. Background technique [0002] Energy dissipation is currently one of the most effective means to reduce the seismic response of the main structure of a building and prevent its collapse in a major earthquake. Anti-buckling bracing is currently being used as a new energy-dissipating and shock-absorbing component in civil and architectural structures. It provides lateral stiffness for the structure during small earthquakes, and yields to dissipate seismic energy during moderate and large earthquakes. In order to provide sufficient rigidity for the structure, it is usually necessary to set up anti-buckling supports 1 (such as figure 1 ), which in turn may affect the setting of door and window openings in the building and reduce the number of openable windows and...
