The great achievement of people, its application expand day by day, no matter from the ground or underground, or even ocean, structural system is more diversified,
The number of plies increases, extended height, progressively position oneself at the forefront in the world, creates record new one by one.
About research show future 50 years, China probably occur it is especially big, there is destructive earthquake, earthquake meeting
A certain degree of negative effect is caused to Chinese society and economic development.So we are necessary to concrete structure bean column node
Performance comprehensively studied, and research and develop new ductile bean column node form, strengthen the anti-seismic performance of bean column node, and in reality
Applied in the engineering of border, reduce casualties and economic loss of the China in earthquake.
Strong column and weak beam is a structuring concept proposed from seismic design of structures angle.It is exactly that post is not broken prior to beam
It is bad, be locality, pillar, which destroys, to jeopardize the safety of total because beam, which destroys, belongs to component damage --- may be whole
Body collapses, and consequence is serious.So to ensure more " relative " safety of post, therefore want " strong column and weak beam ".The mentality of designing of weakening type node
It is by weakening to the beam away from certain distance at beam-to-column joint, promoting plastic hinge to occur and expand in beam weak point
Exhibition, greatly reduces the stress concentration phenomenon of node region, avoids node from occurring crack too early, to reach Ductility Design purpose,
Weak point is equivalent to the effect for serving fuse.Because plastic hinge in the weak point of beam occurs and extended so that longer
One section of beam almost enters plasticity simultaneously, that is, has been truly realized Ductility Design, has given full play to the plastic property of steel, greatly increased
The energy-dissipating property of structure.
Replacement and Repair problem after destruction is another research direction of building field.For being connected by screw bolts, carry
The replaceable component of splice plate, can solve the problems, such as to destroy building damage location quick-replaceable, simple to install, construction is simple, consumption
It is few with material, reduce expense.It is favourable to the repairing construction after destruction, reduce operating expenses, improve the efficiency of construction.

Native beam end plate, described elliptical aperture connector include elliptical aperture splicing steel plate and two connector end plates, and described elliptical aperture is spelled
Connect steel plate both ends and be respectively fixedly connected with connector end plate described in one piece, described two pieces of connector end plates respectively with it is described pre-
Cantilever beam end plate on post processed connects with described beams of concrete end plate, is arranged to replaceable joint form, and dog bone can be achieved
Quick-replaceable after section position is destroyed, simple to install, consumption material is few, reduces expense, has certain economy.
The cantilever beam end plate in the pre-buried described prefabricated post of cantilever beam end in described prefabricated post, described level are mixed
Coagulate the pre-buried described beams of concrete end plate of native beam end.The company described in one piece is respectively welded in described elliptical aperture splicing steel plate both ends
Fitting end plate, described elliptical aperture connector web open elliptical aperture, effectively weaken the strength and stiffness in beam-ends section, in earthquake
By concentration of plastic deformation in beam-ends position, protect node from damage.Two blocks of connector steel plates respectively with described prefabricated post
Cantilever beam end plate and described beams of concrete end plate be connected with.
The beneficial effects of the utility model：The utility model is simple and practical, connects in normal concrete beams close to beam column
Place is met, using steel structure connecting member, oval aperture shape is made in connector web and carries out beam-ends weakening, is realized outside plastic hinge
Move, improve the deformability of node, effectively improve the anti-seismic performance of bean column node；In beams of concrete close to beam-ends junction
Pre-embedded steel slab, it is connected by screw bolts, oval aperture formula steel structure connecting member is turned into replaceable form, realize perforate section portion
Quick-replaceable after position is destroyed, simple to install, consumption material is few, and rehabilitation expense reduces.
