A double broken line tmd control system

Abstract

The invention discloses a double-folded-line type TMD control system. The double-folded-line type TMD control system comprises a body hanging point device, a one-level hanging supporting mechanism, a one-level hanging steel cable, a two-level hanging supporting mechanism, a two-level hanging steel cable and a mass block. The one-level hanging steel cable is connected with the body hanging point device and the one-level hanging supporting mechanism. The two-level hanging supporting mechanism is connected with the one-level hanging supporting mechanism and the two-level hanging supporting mechanism. The position of the connecting point of the two-level hanging steel cable and the one-level hanging supporting mechanism is higher than the position of the connecting point of the one-level hanging steel cable and the one-level hanging supporting mechanism, and the mass block is arranged on the two-level hanging supporting mechanism. According to the double-folded-line system, the effective pendulum length of the TMD control system is increased, accordingly, the basic cycle of the TMD control system is prolonged, then, the effective building storey height can be reasonably utilized, and the vibration control over the long-period structure can be achieved. The mass block is replaced with a fire water tank, and the manufacturing cost is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of TMD, in particular to a double broken line TMD control system. Background technique [0002] TMD is the abbreviation of Tuned Mass Damper (Tuned Mass Damper), which is mainly composed of mass block, spring, damping system, buffer device and so on. At present, most of the control systems on the market are single pendulum TMD control systems, because of their sensitive response to horizontal load excitation, quick start, self-recovery characteristics, simple form, simple design, various single pendulum control forms, and self-vibration period can be controlled by adjusting the pendulum length. and other advantages, so it is widely used in dynamic control of super high-rise building structures and tower structures such as wind vibration and shock absorption, such as Taipei 101 Building, Guangzhou New TV Tower, and Shanghai World Financial Center. In addition, the single-pendulum TMD control system c...

Problems solved by technology

However, the single pendulum TMD control system still has the following disadvantages: first, a large mass block needs to be added to the TMD control system, and the large mass block makes the cross-sectional size of the suspension structure support system larger under the vertical load; second , for super high-rise buildings, due to the long basic period, the pendulum length of the TMD control system also needs to be long, so the setting of the TMD control system has a great influence on the spatial layout of the building

[0003] It can be seen that the above-mentioned existing single pendulum TMD control system obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
