Building integration method and building structure system of TV tower tuned mass damper (TMD) vibration control damping layer

Abstract

The invention discloses a building integration method and a building structure system of a TV tower tuned mass damper (TMD) vibration control damping layer. The building structure system comprises a tower body, a bearing rack (1), an antenna mast (2) and a bearing floor (3). The tower top of a TV tower is provided with a multifunctional damping layer with a TMD vibration control structure; the multifunctional damping layer comprises two large-capacity fire pools and staged pressure pump water supply equipment so that the capacity of the normal high-pressure fire pools can be ensured, wherein the two large-capacity fire pools are arranged symmetrically; the staged pressure pump water supply equipment is used for supplying water to the fire pools; the large-capacity fire pools are used as the main components of mass blocks of the TMD vibration control structure; and the displacement space of the mass blocks is reserved around the two large-capacity fire pools. Because the antenna mast is connected with the tower body in a bearing mode and a large space is formed on the tower top except for a core tube, the invention improves the comfort of the TV tower, integrates vibration control, teaching, science popularization and aesthetic enjoyment and greatly improves the overall level of the building engineering field.

Description

technical field [0001] The invention relates to a building structure system, in particular to a building integration method and building structure system of a TV tower TMD vibration reduction control damping layer. It belongs to the field of construction engineering. Background technique [0002] Tuned Mass Damper (hereinafter referred to as TMD) is generally composed of a mass block, a spring and a damping system. In the prior art, the vibration frequency is generally adjusted to be close to the frequency of the main structure, and the resonance characteristics of the structure are changed to achieve vibration reduction. At present, in the vibration control method of high-rise buildings or towering structures, TMD vibration reduction technology is generally used. Practice has shown that the control effect is best when TMD is placed at the top, and the mass ratio of the mass to the main structure is generally between 0.005 and 0.02. For example, the 101 building in Taipei...

Problems solved by technology

However, when the core tube of a high-rise building or a towering structure is located in the middle of the top floor, the mass block of the TMD vibration damping system cannot be arranged in the center like the Taipei 101 building; especially when the plane area is not enough, it is easy to cause the weight of the mass block to be too small , can not achieve the ideal effect of vibration reduction

Therefore, the vibration control system of the prior art is not suitable for high-rise buildings or high-rise structures where the core tube is located in the center.
