Description
Technical field
The utility model relates to field of civil engineering, and the energy-dissipating type of steel and concrete combination specifically connects beam.
Background technology
The beam that connects shear wall wall limb is called Lian Liang.Lian Liang is the first road anti-vibration defense lines that joins the limb shear wall, and company's beam of appropriate design should be done the time spent in middle shake or big shake and form the plastic hinge seismic energy that dissipates, thus protection agent structure safety, the target of setting up defences of implementation structure " no collapsing with strong earthquake ".Therefore improving the anti-earthquake ductility that joins the limb shear wall mainly realizes by improving the ductility that connects beam.Yet in China's Wenchuan earthquake in 2008, the little span-depth radio of steel concrete couplet limb shear wall structure connects beam and has but occurred shear failure comparatively at large, and shear failure is a kind of brittle failure mode, and its ductility and energy dissipation capacity are relatively poor.Therefore, how improving the shock resistance that connects beam is to join the key issue that presses for solution in the limb shear wall structure.
The company's beam that joins the limb shear wall structure at present mainly contains reinforced concrete coupling beams, steel connects beam and three kinds of forms of steel-concrete composite coupling beams.Wherein reinforced concrete coupling beams is to join limb shear wall structure a kind of beam mode that connects the most commonly used, mainly contains at present by the difference of its reinforcement manner that common parallel arrangement of reinforcement connects beam, the sleeper formula arrangement of reinforcement that intersects connects beam, cross reinforcement connects beam, the rhombus arrangement of reinforcement connects beam, beam and the high strength steel fibre concrete Lian Liang etc. of connecting with seam.Common parallel arrangement of reinforcement connects company's beam reinforcement manner that beam is China " highrise building concrete structure tecnical regulations " (JGJ 3-2011) suggestion; And the seimic disaster census of China's Wenchuan earthquake shows that deformability was poor when little span-depth radio reinforced concrete coupling beams adopted common parallel arrangement of reinforcement; The rotational deformation in cross section is limited in one's ability; It just is tending towards brittle shear and destroys cutting the destruction form of pressure ratio when high slightly, can't realize connecting the requirement of deck-molding ductility and highly energy-consuming ability.For improving the ductility of little span-depth radio reinforced concrete coupling beams, New Zealand Paulay professor T. etc. has proposed intersection sleeper formula arrangement of reinforcement and has connected beam.Have good bearing capacity, ductility and energy dissipation capacity though such connects beam, and adopted, fail to apply in China always because its construction is complicated by multinational standard.For simplifying the construction that intersection sleeper formula arrangement of reinforcement connects beam; Someone has proposed, and cross reinforcement connects beam and the rhombus arrangement of reinforcement connects beam; Company's beam of this form of reinforcement intersects sleeper formula arrangement of reinforcement and connects the beam difficulty of construction and descend to some extent; Its ductility and energy dissipation capacity intersect sleeper formula arrangement of reinforcement to connect beam poor but result of study also shows, do not obtain engineering circle so far and actively adopt widely.In addition, some experimental studies show that rigidity beam, beam with seam and high strength steel fibre concrete Lian Liang etc. also can improve the anti-seismic performance of reinforced concrete coupling beams to some extent.In sum; Because little span-depth radio reinforced concrete coupling beams is because loading characteristic and deformation performance are distinguished common beam; Such calculating and analysis that connects beam becomes quite thorny; Arrangement of reinforcement is also quite complicated with construction, and various countries' seismic design relevant specification still can not be satisfied with about the regulation of reinforced concrete coupling beams design and be solved little span-depth radio and connect not enough this problem of beam ductility at present.
In view of the foregoing; Chinese scholars generally believe adopt steel to connect beam or steel-concrete composite coupling beams at high intensity Zone to replace reinforced concrete coupling beams be to join comparatively desirable selection of limb shear wall structure, wherein steel-concrete composite coupling beams generally is in concrete, to imbed shaped steel or steel plate.But because steel and concrete stiffness difference are bigger, the Lian Liang junction often occur when adopting steel to connect beam and destroy, cause the difficult design that is connected of Lian Liang and shear wall.In addition, traditional U type outsourcing steel-concrete combo box is set a roof beam in place and longitudinal splitting be prone to take place is destroyed and integral slipping destruction, and its reason is that it at steel and concrete filling interface place and at the contact surface of concrete floor and beam slippage takes place easily.Connect beam in addition as the main power consumption member that joins the limb shear wall, require Lian Liangyou energy consume mechanism preferably.
Summary of the invention
