Beam post steel ring hinging section point

Abstract

The invention provides a beam post steel ring hinging section point, which comprises an upright post, a plurality of cross beams, an inner steel ring, an outer steel ring, a post steel ring plug pin and an inter-steel-ring plug pin, wherein the inner steel ring is sheathed on the upright post, the outer steel ring is sheathed on the inner steel ring, the post steel ring plug pin connects the inner steel ring onto the upright post, the inter-steel-ring plug pin connects the outer steel ring onto the inner steel ring, the inner steel ring rotates by using the post steel ring plug pin as a rotating shaft, the outer steel ring rotates by using the inter-steel-ring plug pin as a rotating shaft, a long shaft of the post steel ring plug pin and a long shaft of the inter-steel-ring plug pin are positioned in the orthogonal direction, and during the earthquake, the inner steel ring does limited rotation relative to the upright post and the outer steel ring, so the upright post generates relative movement with the cross beams and a floor slab, further, the mutual traction effect is not generated by each composition component of a building structure, the earthquake effect can be favorably reduced, in addition, the upright post and the cross beams are connected through rigid bonding-pre-stress-free steel bars, the building structure can be enabled to return to the initial position after the earthquake through the elastic recovery force generated by the bonding-pre-stress-free steel bars during the earthquake, and the structural damage caused by earthquakes can also be reduced.

Description

technical field [0001] The invention belongs to the field of building structure engineering and relates to a beam-column connection node. Background technique [0002] Earthquake action and wind vibration force are the main control loads of building structures. The anti-seismic design of traditional building structures is to resist external forces by strengthening the sections of each component. Modern structural control theory believes that the seismic effect of building structures cannot be effectively reduced from the perspective of "resistance", and the new seismic isolation structure system based on structural dynamic characteristics and energy analysis can more effectively reduce the seismic effect. [0003] Nowadays, relatively mature new structural systems based on structural control technology include seismic isolation structural systems and energy dissipation structural systems. The rocking structural system is a research hotspot in recent years. The rocking struc...

Problems solved by technology

[0003] Nowadays, relatively mature new structural systems based on structural control technology include seismic isolation structural systems and energy dissipation structural systems. The rocking structural system is a research hotspot in recent years. The rocking structure reduces the overall lateral stiffness of the building structure by "weakening" The effects of small earthquakes, and by setting energy-dissipating devices such as dampers to control structural deformation, to ensure that the main structure of the building structure is basically intact when it encounters a major earthquake and to facilitate the maintenance of other components, but to achieve the building structure under the earthquake. There are still many difficulties in rocking motion and elastic recovery function, and there is no mature solution at present
