Description

The overlapping profile of tooth steel plate replaceable coupling beam of composite damping energy-dissipating type
Technical field
This utility model relates to skyscraper energy-dissipating and shock-absorbing technical field, particularly relates to the overlapping profile of tooth steel plate replaceable coupling beam of composite damping energy-dissipating type.
Background technology
Owing to land used is nervous, increasing skyscraper or high-rise building are rised sheer from level ground, and become the key character of modern city. Tall building structures system is complicated, expected service life is long, and it mostly is residential houses, city commercial financial center, population in use is numerous, once experience eaerthquake damage, huge economic loss will be produced, productive life and social stability to the people cause and have a strong impact on, and skyscraper repairing and reinforcement difficulty, take time and effort, some component is because the particularity of destruction position and destruction seriousness make it be difficult to reinforcement and repair, last total can only be overthrown reconstruction, adds the life cycle cost of whole building, causes huge waste. Therefore, after promoting modern high-rise building shake, function fast restoration capabilities is extremely urgent.
Shear wall structure is anti-side system the most frequently used in skyscraper, and owing to building the needs of door window and Ductility Requirement, shear wall punching internal interruption-forming coupling beam, different wall limbs are connected by coupling beam and are able to collaborative work and jointly resist geological process. Shear wall anti-seismic performance is had important impact by the intensity of coupling beam, rigidity and deformation performance. Under normal use and frequently occurred earthquake effect, coupling beam works in elastic range, connect the adjacent wall limb of shear wall, ensure the anti-side rigidity of structure, tradition coupling beam does not have damping performance when little shake, skyscraper meets the requirement of Bit andits control index when little shake only by raising rigidity, and after improving rigidity, the geological process on usual building also can increase. Under fortification intensity or rarely occurred earthquake effect, coupling beam is as the first anti-vibration defense lines of shear wall structure, occur to destroy prior to wall limb and enter plastic dissipation seismic energy, but the general span-depth radio of traditional reinforced concrete coupling beams is less, under earthquake reciprocating, easily occur brittle shear failure, ductility poor, be difficult to after shake repair, also cannot change.
Past, crowd scholar mainly improved the ductility of tradition coupling beams from two angles, and one is adopt different construction measures or reinforcement manner, set seam, configuration intersection dark support, rhombus arrangement of reinforcement etc. in coupling beam. Two is replace traditional reinforced concrete coupling beams composition mixing Coupled Shear Wall structure with steel coupling beam or composite coupling beams.Both modes all can to a certain degree improve coupling beam ductility, but its common shortcoming is to be designed without the recoverability after taking into full account shake or convertibility, is not easily repaired or changes after shake.
The new ideas that functional structure is current seismic design can be recovered, need not repair after referring to earthquake or slightly repair under part behaviour in service and can recover its structure using function, its implementation includes replaceable structural elements, swinging structure, Self-resetting structure etc., therefore, recent domestic scholar proposes the concept of replaceable coupling beam, contain the current replaceable coupling beam of existing all kinds, i.e. a kind of coupling beam being prone to repair or change after earthquake, coupling beam self can be reinforced concrete coupling beams, steel coupling beam or composite coupling beams, its make includes the partial cross section of coupling beam is weakened, or additional damping energy dissipation parts in coupling beam, or coupling beam is connected with body of wall entirely through certain mode being readily disassembled, after earthquake, coupling beam can be conveniently carried out changing.
At present, existing replaceable coupling beam is mostly by replaceable section of surrender power consumption, but its weak point replaceable energy-consuming parts that is some does not take into full account the reasonability of its stress, causes that Energy dissipating material tension produces to tear, thus affecting giving full play to of its power consumption effect; And although some replaceable coupling beam improves its energy dissipation capacity to a certain extent, but weaken the performance of coupling beam and Coupled Shear Wall collaborative work or change the power transmission feature of coupling beam between wall limb, bringing difficulty to designer when structured design phase application commercial design software is calculated and analyzing. The replaceable coupling beam of majority proposed at present cannot be changed according to the power of earthquake sub-unit stage by stage, and the cost changed completely after shake is higher.
