PBL puts more energy into shape steel tube concrete joint.
Background technique
Rectangular steel pipe girders structure have many advantages, such as it is big, easy to make from heavy and light, good appearance, cross sectional moment of inertia, it is wide
It is general to be applied in ocean platform, roof structure and science of bridge building.Coagulation is filled in the chord member of rectangular steel pipe girders structure
Soil forms Concrete-Filled Rectangular Steel Tube Truss structure, and the stress performance and entirety that can further improve rectangular steel pipe girders structure are just
Degree.
Since the node of rectangular steel pipe girders structure is in such a way that chord member and web member directly weld, rectangle steel is usually become
Whether most weak link in tube truss structure, node are rationally not only directly related to integrally-built reliability, but also to knot
The cost of the construction quality of structure, project progress and entire engineering has direct influence.
Currently, the most common joint form in rectangular steel pipe girders structure are as follows: a web member tension in K-type node, one
Root web member is pressurized.Existing K-type node has the following problems: 1, in bridge structure, chord member width is too small and height is excessive, causes
Stock utilization is low, and shear connector and support lay insufficient space, influences structure tension performance.2, tension web member is mostly rectangle sky steel
Pipe, due to the presence in web member gap, web member center line and chord member center line can not be intersected in a bit, that is, there is node eccentricity,
Node is caused to generate additional bending moment, ultimate bearing capacity of joints reduces.3, the design of tension web member shape is unreasonable, and tension web member is caused to transmit
Axial force directly born by relatively weak chord member top plate anti-bending bearing capacity, steel tensile property be not not fully exerted and
Premature failure causes the waste of material.4, compression web member size design is unreasonable, and when leading to destruction of a node, web member bearing capacity is deposited
It has more than needed larger, causes the waste of material.5, steel pipe and concrete globality poor in chord member, are easy to produce concrete unsticking etc. and ask
Topic.The presence of these problems seriously constrains the application of Concrete-filled tubular connections in engineering practice.
Therefore, how to research and develop a kind of with stock utilization is high, stress performance is superior, joint form convenient for construction, show
It obtains particularly important.
