Description
Technical Field
The utility model relates to a shaped steel concrete's shock attenuation field, concretely relates to assembled antidetonation steel pipe concrete toughness post.
Background
At present, the 'three-level' seismic fortification target is adopted in 'building seismic design specifications' (GB50011-2010) in China to carry out seismic design on a structure, namely 'small earthquake is not damaged, medium earthquake can be repaired, and large earthquake is not fallen'. With the continuous and rapid development of national economy in China, the earthquake resistant level of many regions can basically avoid casualties, and small earthquake damage and large earthquake collapse are realized, but the structure after the earthquake is usually reinforced or dismantled due to overlarge plastic deformation, so the cost or indirect loss is even higher than the construction cost, and medium earthquake repairable cannot be realized. Therefore, the control of the residual plastic deformation of the structure is more and more emphasized by the owners and researchers, and has become an important index for the design and evaluation of the performance-based earthquake-proof.
The self-resetting steel frame structure is a novel structural form which provides self-resetting force for the structure through tensioning the pre-pull rod, and can effectively reduce the residual deformation of the structure after the structure is subjected to the earthquake action. Under the action of a small earthquake, the joint gaps of the self-reset steel frame structure beam columns are not opened, and the structural members are kept elastic like a bending-resistant frame; under the action of medium or large earthquake, the self-resetting steel frame structure props against the opening gap through the beam-column node, so that the energy dissipation component arranged at the node consumes earthquake energy to reduce or even avoid the damage of the main body structure, and the gap is closed by the pre-pull rod after the earthquake action to realize the self-resetting function. Through the adjustment of the size of the energy dissipation member, the number and initial tension of the pre-pull rods and the size of the beam column member, the rigidity, bearing capacity, ductility and hysteresis performance of the self-resetting steel frame structure under the action of lateral load can be changed, and the special performance can facilitate the adjustment of structural rigidity matching of different parts by engineers during structural design.
However, the column pitch of the traditional self-resetting steel frame structure is increased along with the expansion of the beam-column joint, and a complex floor arrangement form is required to avoid the tensile cracking of the floor when the column pitch is increased. In addition, the traditional self-resetting steel frame structure usually needs to be subjected to tensioning of a pre-pull rod and welding of components on a construction site, is not beneficial to ensuring construction quality and has high construction difficulty, so that the application of the self-resetting frame in actual engineering is limited, and the problems that the initial rigidity is low, the connection of beam columns is easy to break and the like can be solved by the currently proposed double-beam self-resetting steel frame, so that the application of the self-resetting double beams in actual engineering is seriously influenced.
