Description
Technical field
This utility model is related to brick or concrete duct field, and specifically a kind of prestressing force Self-resetting damages controllable assembly and waves wall.
Background technology
Earthquake often causes huge social influence and economic loss as paroxysmal natural disaster.According to specification
The normal concrete building of design can not fully meet the growing antidetonation demand of building.Structure is needed in calamities such as earthquakes
The lower structural damage of evil effect will not excessive development, can be under rational technical conditions and economic condition through repair can be extensive after calamity
Multiple its expectation function, that is, damage controlled architecture.
Structural damage is presented as the general effect of component damage, including damage type, degree of injury and damage profile three
Aspect.The purpose of structural damage control is that the damage of structure is limited in position set in advance, and makes these positions pre-
Degree of injury under phase macroseism is less than predetermined limit value, and residual deformation of the structure after shake is less than predetermined limit value.
Damage generally has following both sides effect to structure：After damage, the rigidity of structure is reduced, cycle stretch-out.This typically can
Increase the dynamic respond of structure, but the seismic force that structure is subject to can also decrease；It is certain that damage location tends to dissipation
Inputting seismic energy, so as to reduce the seismic response of structure.Therefore controlled damage for structural seismic performance be favourable.Knot
The following two common feature of expected damage location in structure system：There is larger tribute to the overall anti-side rigidity of structure before damaging
Offer；Little is affected on the vertical bearing capacity of structure after damage.
Efficiently control the deformation pattern of structure, exclude the dry of the randomness that caused by each side factor such as geological process
Disturb, be the key for realizing expected damage profile；Reduce the discreteness of structure deformation pattern under macroseism, structure can be made in macroseism
Under Seismic response be more prone to prediction so that the Aseismic Design of structure is relatively reliable.
In actual seismic demage analysis, the bottom shear wall destruction in shear wall structure or frame-shear-wall structure is very tight
Weight.Researchers have found that basic suitably lifting often contributes to reducing the geological process of superstructure, so as to mitigate structure shake
Evil.System is waved in the researcher proposition that takes the lead in of the country such as U.S., and the system passes through the constraint between loosening configuration and basis or component,
Allow certain part of structure or structure to wave under geological process, and utilization wave some positions of structure for causing can
Control deformation, by Damage Coutrol on " waving interface ".
It is existing at present to wave wall member, in addition to some special architectural appearances, it is difficult to mutually coordinate even with overall structure
Situation such as floor cracking etc. that agent structure is destroyed after waving wall lifting occurs.One monoblock wall is pre- from bottom to top soap-free emulsion polymeization
The applying of stress increased the unreliable degree of structure in earthquake.The existing building industrialization concept for waving wall design is not enough,
Structural strengthening field is also difficult to apply, and quick reparation is difficult to after shaking.
