Description
Technical Field
The invention relates to a shearing energy consumption section and a construction method thereof, in particular to a sectional shearing energy consumption section with an energy dissipation core and an installation method thereof, and belongs to the technical field of building structural engineering.
Background
In the assembled frame, the connecting part of the precast beam columns is a key stress position of the main body structure, and is called a node core area; the area is usually under the coupling action of multiple factors such as bending moment, shearing force, axial force and the like, and the stress mechanism is relatively complex. For an assembled concrete column-steel beam mixed frame, the node damage is often serious because of the problem of unsynchronized damage of steel and concrete materials under the action of cyclic load.
At present, node damage control is often realized by arranging a dog-bone type weakening area and the like on a beam section, and the node damage control can play a role in protecting the node connection area, but the structural bearing capacity can be reduced due to the weakening section, so that the economy of the overall structural design is affected; meanwhile, the weakened steel beam end is bent to form a plastic hinge, but the section of the steel beam is often smaller due to the restriction of the ratio relation of the beam and the column in the assembled concrete column-steel beam mixed frame, so that the bending moment hinge formed in the weakened area is often poor in hysteresis performance, the structural seismic performance and the post-earthquake repair performance are poor, and the application range is limited.
20. Early in the 70 s of the century, a steel structural system modified to take up the advantages of both a bending steel frame and a center support, called an eccentric support steel frame (EBF), was proposed in japan. Compared with the central support steel frame, the eccentric support steel frame can accurately and effectively control the deflection of the structure under the horizontal earthquake, and reduce the lateral movement of the interlayer and the whole structure; the shear yield of the energy dissipating beam section acts like a "fuse" dissipating excessive energy in the event of an intense earthquake. The key section Liang Wei of the eccentric support steel frame with stiffening ribs is the energy-consuming beam section. However, the existing shearing energy consumption section has single form, poor deformability, larger influence of axial force on mechanical properties and poor replaceability after earthquake.
