Description

A kind of replaceable bean column node seismic Damage control device

Technical field

The present invention relates to Construction Anti-earthquake technical field more particularly to a kind of replaceable bean column node seismic Damage controls Device processed.

Background technology

Steel construction has the characteristics that intensity height, light weight, anti-seismic performance be good, short construction period, it is considered to be anti-seismic performance One of best structure type.With Steel Structural Design and manufacture, the development of mounting technique, the application in engineering practice is got over Come more extensive.But a large amount of Disaster Datas show with experimental study:Under geological process, stress value is larger at the node of beam column, especially It is that brittle fracture easily occurs for steel near welding position, seriously affects safety of the structure under earthquake, and causes to build Build quick-recovery can not use after earthquake soon.

The generation of brittle fracture occurs in order to reduce steel structure frame bean column node under geological process, and ensures Vierendeel girder Still preferable ductility can be kept after surrender, to have the function that dissipation seismic energy, scientific research is a series of with being proposed in engineering Corrective measure, including weakening beam-ends section, improving welding connection structure etc..Wherein, beam-ends weakening process is that artificial weaken connects The flange section up and down of near nodal beam makes beam weaken the power of the bearing capacity less than destruction of a node needs in section, can not only keep away Exempt from node and brittle fracture occurs, the plasticity energy dissipation capacity after can also being surrendered using beam is come the seismic energy that dissipates.

A large number of experiments show that such node shows good ductility under geological process, but it is lacked there is also apparent It falls into and insufficient:First, stress concentration is generated weakening section in order to prevent, in work progress to the required precision of processing technology very Height, complex procedures, long construction period, economy consumption are big.Secondly, it is with the development of economy, continuous to the shockproof requirements of building It improves, in the basic demand for no longer only residing within " no collapsing with strong earthquake ", it is required that building can be recovered to use as early as possible after earthquake, Weakening the damage at position and deformation can cause building to be difficult to repair or quick-recovery can not use soon, bring huge economic cost. Quick replacement or reparation damaged part after earthquake recover building using function, reduce direct caused by strong earthquakes destroy as early as possible And indirect loss, it is the necessary links for promoting China's earthquake disaster defence integral level.Therefore, such node by macroseism with Afterwards, beam-ends forms plastic hinge, has larger residual deformation, it is impossible to realize the target of quick replacement or reparation, it is necessary to further Improve.

The content of the invention
