Description
Technical field:
The present invention relates to construction applications, specifically a kind of novel controlled waves shock-damping structure system.
Background technique:
Novel damping structural system has runback bit architecture, swinging structure, recoverable function structure etc..Runback bit architecture passes through
Loosen certain joint constraint, in the structure be added presstressed reinforcing steel come reduce seismic structural response and provide self-resetting capability,
Residual displacement is small after shake, and strength and stiffness reduce less, is easily repaired and quickly puts back into, earthquake can be greatly decreased and make
At economic loss.
Self-centering (post-tensioned self-centering) structural system of post stretching is to reduce residual deformation
And it proposes.This structural system is made of self-centering system and dissipative devices.Self-centering system is by post-tensioning reinforcing bar or steel strand wires
Composition makes heart function by oneself to provide.Dissipative devices are to provide energy consumption by surrender, bonding, friction by support or damper
Function.Post stretching self contering structure system, which has, to be reduced maximum distortion and reduces residual deformation, reduces the excellent of structural elements damage
Point.
The damage of structural elements is reduced or avoided by waving structure, provides recovery function, limitation pair for swinging structure
The requirement of non-structural element.The behavior of waving in swinging structure can (posttensioned tendons provide self-centering by self contering structure
Function) or structure itself gravity (suspension column be lifted and fall) provide.Energy dissipation capacity in swinging structure is bent by steel
The viscous damping devices (interchangeable angle steel etc.) that suspension column was set and be placed in clothes provide, with the reaction of control structure.Suspension column is set
Meter will allow suspension column to be lifted.
Wherein, presstressed reinforcing steel is provided in this mode of restoring force, the restoring force meeting provided when undergoing geological process
Its specific function is reduced because of the damage of presstressed reinforcing steel, and therefore influences the control for deforming with destroying to building structure.It is high-rise
In building structure, accumulated in column by superstructure transmit it is axial draw, pressure is transmitted in basis when, dead load will
It is not enough to offset whole axial tensions, after the axial tension accumulated in column overcomes dead load, it is difficult to guarantee frame column and structure
Safety, stability and the integrally-built effective force path on basis.
Therefore it proposes a kind of novel controlled waves shock-damping structure system, is adopted based on displacement sensor and data collection system
The displacement data of collection, predicts the input direction of earthquake motion, thus controls the direction of relative movement of semi-automatic electromagnetic damper, in turn
Contrary moment of flexure is moved to structure offer, so that structure generation is waved behavior, so that the relative storey displacement of structure subtracts
Small, structural damage is reduced.
