Abstract
The invention relates to a structure for strengthening anti-seismic performance of a steel frame, in particular to an anti-seismic structure of an energy-consumption angle brace. The anti-seismic structure of an energy-consumption angle brace comprises a frame beam and a frame column, wherein the node position of the frame beam and the frame column is provided with an energy-consumption angle brace plate; and the contact surface between the energy-consumption angle brace plate and the frame beam as well as the contact surface between the energy-consumption angle brace plate and the frame column are respectively fixedly connected by a connecting plate. The anti-seismic structure of an energy-consumption angle brace is favorable for flexible arrangement of frame structure space and is favorable for the arrangement and construction of a filler wall. Under the condition of no seism or under the condition of quaking frequently, the energy-consumption angle brace can perform the action of acommon angle brace to protect the node; under the action of seldom-occurred seism, when the beam and the column have great relative rotation, the energy-consumption plate of the energy-consumption angle brace can yield, energy can be continuously adsorbed and consumed by being continuously pulled and stressed to yield, and on the effects of supporting the beam and the column and protecting the node can be kept so as to protect the safety of the node, avoid node damage and reduce seismic damage.
Description
Technical field
The present invention relates to a kind of structure that strengthens the steel frame anti-seismic performance, particularly relate to a kind of earthquake resistant structure of the angle brace that consumes energy.Belong to multilayer and this technical field of highrise building technology.
Background technology
At present, many high-rise frame structures are when carrying out seismic design, in order to guarantee integrally-built safety, generally all adopt the design principles of " the weak member of strong node ", to guarantee under middle chance or rarely occurred earthquake effect, when main lateral resistant member such as beam, post entered yield situation, the node that connects these members did not at first destroy.In case connected node destroys, structural element can not play a role by force again.Follow the design principles of " the weak member of strong node ", not only can protect main lateral resistant member such as beam, post, also can reduce integrally-built geological process by the plasticity circulation power consumption of these lateral resistant member.
In addition, traditional design with analyze bean column node with framework and be divided into and be rigidly connected, be articulated and connected or semi-rigidly be connected three kinds of types of attachment.Generally, the framework of opposing side force is connected with beam, post bending resistance, all adopts rigidly connected node connectivity scenario.Though do not relatively rotate between rigidly connected node beam column in theory, actual in loading process, can inevitably produce relative rotation between the beam column.Be articulated and connected and semi-rigid connected node, thinking in theory has relative rotation between its beam column.Beam column relatively rotates and must control within certain scope, otherwise destruction of a node will take place, irresistibly the earthquake calamity evil.
Summary of the invention
The present invention is directed to the technical problem of above-mentioned existence, provide a kind of rational in infrastructure, cost is low, can the frame space that use not impacted, be convenient to layout and the construction of infilled wall, relative rotation during earthquake between the operative constraint frame beam column, save steel using amount, promote speed of application, guarantee the earthquake resistant structure of a kind of angle brace that consumes energy of frame joint rigidity.
The technical scheme of technical solution problem of the present invention is to achieve these goals:
A kind of earthquake resistant structure of the angle brace that consumes energy comprises: Vierendeel girder, frame column, and it is: the node location of Vierendeel girder and frame column is provided with power consumption angle brace plate; This power consumption angle brace plate is connected by junction plate respectively mutually with Vierendeel girder and frame column contact surface.
Described power consumption angle brace plate is triangle or one of trapezoidal.
The adapting position of described power consumption angle brace plate is provided with stiffening rib.
The present invention compared with prior art has following advantage and effect:
The present invention is conducive to frame construction space flexible arrangement owing to adopted the power consumption angle brace to be arranged on the bean column node position, is conducive to layout and the construction of infilled wall.Under no earthquake or frequently occurred earthquake effect, the power consumption angle brace can play the effect of general angle brace, namely limits beam column and relatively rotates, and strengthens joint rigidity, the protection node; Under the rarely occurred earthquake effect, beam column relatively rotates when excessive, and the power consumption plate surrender of power consumption angle brace by tension and pressurized surrender constantly, can absorb seismic energy, reaches the purpose of energy-absorbing energy-dissipating, reduces earthquake disaster.Simultaneously; because power consumption angle brace plate length is shorter; and the influence of stiffening rib is arranged; can make power consumption angle brace plate before strength failure takes place, unstable failure outside the plane not take place; thereby guarantee to make power consumption angle brace plate tension pressurized flexing can continue to carry out; i.e. continuous energy-absorbing energy-dissipating; it is lost to the supporting role of beam column with to the protective effect of node; the reinforced frame node strength; strengthen frame construction rigidity, reduce relative storey displacement, thus the protection node security; unlikely formation destruction of a node; reduce earthquake disaster, the present invention is rational in infrastructure through experimental results show that repeatedly; with low cost, save steel using amount; promote speed of application, guaranteed the shock resistance of frame joint rigidity greatly.
