Problems solved by technology
[0007] However, both traditional TMD and BRB have their own limitations: TMD takes up a lot of building space, is sensitive to changes in structural modal properties, takes a long time to start, and takes effect slowly. It has good wind-induced response and poor seismic response.
BRB has the problems of yield force limitation and material fatigue resistance. It has excellent seismic performance, but it has poor control of environmental vibration.

Embodiment Construction
[0033] Embodiments of the present invention are described in detail below, as Figure 1-6 As shown, the upper gusset plate 1 and the lower gusset plate 2 are first connected to the main structure 13, and then the steel core 3 is connected to the upper gusset plate 1 and the lower gusset plate 2 to form an oblique support system. If the main structure is a reinforced concrete structure, the upper gusset plate 1 and the lower gusset plate 2 can be connected to the main structure by pre-embedded pouring technology; if the main structure is a steel structure, the welding process can be used to connect to the main structure. The connection between the steel core 3 and the gusset plate is welded or bolted.
[0034] A bearing platform 12 is arranged on the lower surface of the main structure, and a sliding track 10 is placed on the bearing platform. The height of the platform should ensure that after installation, the lower surface of the mass source front side assembly 4a and the m...

The invention discloses a shock-absorbing wall device. An upper portion joint plate and a lower portion joint plate are connected with a main structure in the panel in the height direction of the mainstructure in a diagonal mode, and a steel core is connected with the upper portion joint plate and the lower portion joint plate to form a single inclined support system together with the main structure. A bearing platform is arranged on the lower surface of the main structure, a track is paved on the bearing platform, and limiting clamps are slidably arranged on the two ends of the track. A tuned mass damper (TMD) is formed by combining a mass source front side component, a mass source rear side component, an upper portion limiting plate and a lower portion limiting plate. Pulleys are arranged on the lower surfaces of the mass source front side component and the mass source rear side component, then the pulleys are placed on the track, certain space is reserved in the middle of the masssource, and the steel core is clamped in the middle of the space. The resilient elements and damping elements are arranged between the end portion of the mass source and the main structure, and the shock-absorbing wall device with double functions of tuned mass and metal yield energy dissipation and shock absorption is formed is formed.
Description
[0001] This application is a divisional application of the invention patent application "Tuning Mass Type Yield Energy Dissipation Shock Wall Device". [0002] The original filing date: 2016-07-08. [0003] Original application number: 2016105330083. [0004] Invention name of the original case: tuned mass type yield energy dissipation shock-absorbing wall device. technical field [0005] The invention relates to a shock-absorbing wall device and a method for determining the type and quantity of rebound elements, which relate to the energy-dissipating and shock-absorbing technology of civil engineering structures. Background technique [0006] The tuned mass damper (TMD) is one of the widely used technologies in building vibration control at present. Partially offset the disturbing force input to the structure. Buckling-resistant bracing (BRB) is to arrange unbonded constrained units around the steel core to improve its stability, and then realize energy dissipation and s...
