Description
Technical field
The invention belongs to civil engineering Aseismic Structure System technical fields, and in particular to a kind of ductility coupling beam waves steel frame
Structural system.
Background technique
In recent years, earth some areas enter Earthquake Activity Periods, and the earthquake of larger earthquake magnitude all occurs for the multiple places in the whole world,
Earthquake disaster it is new tendency be that economic loss caused by disaster is extremely huge, disaster occur after it is huge reconstruction and reparation at
This, so that " toughness is taken precautions against natural calamities " becomes research trend of taking precautions against natural calamities new at present.Disaster Prevention Design towards " toughness " is exactly to pass through promotion work
The Disaster Defense Capability of journey structure, or the recovery difficulty of control engineering structure disaster, thus when reaching reduction earthquake loss and restoring
Between target.
Damage mode of the existing steel frame structural system under geological process and energy consumption position control difficulty are larger, " strong
The global failure mode of the weak beam of column " is difficult to ensure, and the damage of calamity rear part is serious, residual deformation is big, repairs difficult.Swinging structure
System is waved by structural integrity as one of the structural system with recoverable function and prevents weak floor, make structure
Each layer stratified deformation reaches unanimity, to reduce the damage of residual deformation and main structure component, realizes the need of " toughness is taken precautions against natural calamities "
It asks.
Therefore, the present invention is by separating the bearing function of traditional steel frame structural system with energy consumption function, in conjunction with waving
The technical concept of structure, runback bit architecture and energy-dissipating and shock-absorbing, it is intended to which fast quick-recovery uses function after designing the achievable shake of one kind
New structural systen.
Summary of the invention
It is an object of the invention to propose that a kind of ductility coupling beam waves steel frame structural system, which passes through two sides steel branch
Support frame frame provides lateral rigidity and recovery capacity, replaceable coupling beam and swing suspension column dissipation seismic energy.
To achieve the above object, the invention adopts the following technical scheme:
A kind of ductility coupling beam waves steel frame system, is mainly made of multiple bracing members frames, passes through between bracing members frame
Replaceable coupling beam 4 and energy-dissipating type bean column node 5 cooperate, and realize connection;The frame column 2 of bracing members base of frame is connected with swing
Suspension column 6 realizes lifting and the return of bracing members frame by swing suspension column 6;
The bracing members frame is mainly made of Vierendeel girder 1, frame column 2 and bracing members 3, for bearing vertical load,
And lateral rigidity is provided, elasticity is remained by allowing bracing members base of frame that lifting occurs under geological process;Steel branch
Steel frame system is waved by replaceable coupling beam 4 and the mating connection composition ductility coupling beam of energy-dissipating type bean column node 5 between support frame frame, when
When the ductility coupling beam waves steel frame system by geological process, by 6 dissipation seismic energy of replaceable coupling beam 4 and swing suspension column
Amount, protects two sides bracing members frame not destroy.
Vierendeel girder 1, frame column 2 and the bracing members 3 are the steel member section shape of i shaped cross section or square steel tube section
Formula;Vierendeel girder 1 is welded between two frame columns 2, forms multiple basic frameworks, and bracing members 3 are respectively welded at frame by gusset plate 7
