Abstract

The invention relates to the technical field of vibration reduction and disaster prevention of building structures, and discloses a novel sliding TMD capable of adjusting frequency continuously. The novel sliding TMD comprises a spring, an adjusting plate, a rotary connecting plate, a damper, a mass block and a support, wherein the adjusting plate, the spring and the damper are arranged on the support; the adjusting plate and the spring are separately arranged at two ends of the support; the rotary connecting plate is arranged above the support; one end of the rotary connecting plate is rotatably connected with the adjusting plate; the other end of the rotary connecting plate is supported through the spring; the mass block is slidably arranged on the rotary connecting plate; the height ofthe rotary connecting plate relative to the support is adjustable; and the position of the spring on the support is adjustable. The problems that the frequency of a frequency adjusting mass damper cannot be adjusted continuously, and a frequency adjusting range is small are solved.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and disaster prevention of building structures, and discloses a novel sliding TMD capable of continuous frequency modulation. Background technique [0002] With the development of urban construction, the urban transportation network has become more and more developed, and various structures such as long-span bridges, corridors, large roofs, and high-speed rail station buildings have been widely used, bringing great convenience to people's lives . However, although the strength and stiffness of this type of building are relatively easy to meet the design requirements, the frequency of its vertical vibration is generally relatively low, and it is prone to resonance under the action of wind load, pedestrians, vehicles and other dynamic loads, resulting in damage to the bridge itself. Even seriously threaten the safety of pedestrians and vehicles. In addition, some thin and tall building...
