Description
Technical field
This utility model is related to Construction Anti-earthquake technical field, and more particularly, to a kind of removable bean column node ground is damaged
Hinder control device.
Background technology
Steel construction has that intensity height, light weight, anti-seismic performance be good, short construction period the features such as it is considered to be anti-seismic performance
One of best version.With the development of Steel Structural Design and manufacture, mounting technique, its application in engineering practice is got over
Come more extensive.But a large amount of Disaster Datas are shown with experimental study: under geological process, at the node of beam column, stress value is larger, especially
It is that steel near welding position are susceptible to brittle fracture, badly influences safety under earthquake for the structure, and leads to build
Build and cannot quick-recovery use soon after earthquake.
There is the generation of brittle fracture in order to reduce steel structure frame bean column node under geological process, and guarantee Vierendeel girder
Still preferable ductility can be kept after surrender, to reach the effect of dissipation seismic energy, propose a series of in scientific research and engineering
Corrective measure, including weakening beam-ends section, improves welding connection structure etc..Wherein, beam-ends weakening process is that artificial weakening connects
The flange section up and down of near nodal beam, makes the bearing capacity that beam weakens section be less than the power that destruction of a node needs, not only can keep away
Exempt from node and brittle fracture occurs, be also with the plasticity energy dissipation capacity after beam surrender come the seismic energy that to dissipate.
A large number of experiments show that such node shows good ductility under geological process, but it there is also and substantially lacks
Fall into and not enough: first, in order to prevent producing stress concentration weakening section, in work progress to the required precision of processing technique very
Height, complex procedures, long construction period, economic consumption is big.Secondly, with expanding economy, continuous to the shockproof requirements of building
Improve, no longer only reside within the basic demand of " no collapsing with strong earthquake ", it is required that building can be recovered to use as early as possible after earthquake,
Weaken the damage at position and deformation may result in building to be difficult to repair or cannot quick-recovery use soon, bring huge economic cost.
Quick replacement or reparation damaged part after earthquake, recover building as early as possible and use function, it is direct that minimizing causes because strong earthquakes destroy
And indirect loss, it is an up the necessary links that China's earthquake disaster defends integral level.Therefore, such node suffer from macroseism with
Afterwards, beam-ends forms plastic hinge, has larger residual deformation it is impossible to realize the target of quick replacement or reparation, needs further
Improve.
