Vibration and earthquake integrated control structure for building construction above subway and design method

Abstract

The invention provides a vibration and earthquake integrated control structure for building a construction above a subway and a design method thereof. The vibration and earthquake integrated control structure comprises a construction base, a construction foundation, a vibration isolation layer between the construction base and the construction foundation, the vibration isolation layer comprises steel spring absorbers and viscous dampers, wherein the steel spring absorbers are arranged at corresponding positions below the main structural columns of the construction, and the viscous dampers areconnected between the construction foundation and the construction base around the construction. On the basis of this structure, the complete and feasible design method of quantitative analysis and integration has been established. The vibration and earthquake integrated control structure and the design method can meet the requirements of vibration control and operation of the subway as well as earthquake-proof fortification at the same time, and replacement and maintenance are convenient.

Description

technical field [0001] The invention relates to a vibration-seismic integrated control structure and design method of a subway superstructure, belonging to the technical field of engineering vibration reduction and isolation technology. Background technique [0002] At present, many buildings only have anti-seismic design, no vibration isolation design, or use vibration-absorbing pads or rubber shock absorbers for vibration isolation. However, in the subway superstructure, adjoining, and cross-construction projects, the operation of the subway will cause disadvantages to the buildings. Influence, it is necessary to carry out vibration isolation on the superstructure of the subway. Generally, it is necessary to set up a vibration isolation layer, and rubber shock absorbers are often used to reduce vibration. There is no uniform standard and design process, and most of them rely on experience to design vibration isolation schemes, or directly apply the schemes of similar exist...

Problems solved by technology

[0005] In order to solve the adverse effects of subway operation on buildings in subway superstructure, adjoining and cross-construction projects, the present invention proposes a vibration-seismic integrated control structure of subway superstructure and its vibration reduction and anti-seismic design method. It sets a vibration isolation layer under the building foundation, supports the building structure including the foundation as a whole, and sets vibration isolation joints around it. This structure and technology can meet the requirements of building vibration without changing the design parameters of the upper structure of the building. Control requirements and anti-seismic fortifications under rare earthquakes to ensure the normal use of buildings and the safety of people under the action of earthquakes
