Conceptual design method of multiple lines of defense for vibration control of building structures

Abstract

The invention discloses an engineering technical process of a conceptual design method for controlling multi-line defense lines in vibration of a building structure, which mainly includes design methods for avoiding multiple lines of defense, that is, avoidance design for new buildings and avoidance design for existing buildings; design method for multiple lines of defense in space , that is to take active control measures for the vibration source, take control measures such as extending the transmission path or setting up various transmission barriers for the transmission path, and take active and passive control measures for vibration-sensitive objects; the multi-line defense design method in time, that is, periodic vibration Control design and predictive control design.

Description

technical field [0001] The invention relates to a conceptual design method of multiple lines of defense for building structure vibration control, which belongs to the field of building design. Background technique [0002] At present, there are few professional specifications for the vibration control of industrial and civil building structures, and the complete set of technical methods is still immature. Aspects such as building structures and process equipment are susceptible to vibration and cause various vibration hazards. In the past, most of the following control methods were used: conventional rigid design methods for building structures; separate vibration reduction and isolation design for power equipment and separate isolation for process equipment vibration design. [0003] The role of these design schemes in actual vibration control engineering is often partial, one-sided, and temporary, and does not consider the integrity, stages, and whole process, so it has t...

AI Technical Summary

Problems solved by technology

[0005] The design of vibration reduction and isolation of power equipment alone is only a brief and flexible design for the foundation of power equipment, pipe support and hoisting, etc., and lacks a global design for the dynamic characteristic parameters of all power equipment inside the building structure, resulting in that despite the vibration reduction and isolation Design, but with very limited control and sometimes counterproductive

[0006] The design of vibration reduction and isolation of process equipment alone lacks comprehensive consideration of the vibration source and transmission path around it, and it is impossible to solve the problem of vibration hazards in complex building structures in engineering by relying on a single technical means.
