Problems solved by technology

However, the high uncertainty of seismic load, the nonlinearity of materials and the variation of performance during use, as well as the limitations of existing structural analysis and design methods make it possible that the structure does not meet the requirements of function and safety.

Embodiment Construction

[0056] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0057] Such as figure 1 Shown, the optimal design method of the TMD that the present invention installs spring-mass system comprises the steps:

[0058] Step 1, from the mass m of the main building structure itself s , damping c s and stiffness k s , on the basis of a single tuned mass damper (TMD), a small mass is added between the main structure of the building and the single tuned mass damper, between the mass of the main structure of the building and the small mass, the small mass An additional spring is added between the single tuned mass damper, and then the mechanical model of the main structure of the building—installed spring-mass system tuned mass damper is established;

[0059] Step 2, according to the principle of dynamics of the main building structure, analyze the force of the main building structure, a single tuned mass da...

Abstract

The invention discloses a TMD (Tuned Mass Damper) optimal design method of an installation spring-quality system. The TMD optimal design method comprises the following four steps: 1) establishing a TMD system model of a structure-installation spring-quality system; 2) establishing a TMD system and a kinetic equation of the structure-installation spring-quality system; 3) applying a simulated annealing algorithm to carry out optimal computation on the TMD of the installation spring-quality system; and 4) through comparison, selecting an optimal combination parameter to design the TMD of a novel installation spring-quality system. The TMD optimal design method has an innovation that the TMD, which is suitable for all structures, of the novel installation spring-quality system is designed. The TMD of the novel installation spring-quality system has the advantages that the displacement response of the structure under an earthquake action can be effectively controlled, and the TMD of the novel installation spring-quality system is superior to the TMD.

Description

technical field [0001] The invention relates to a design method for installing a spring-mass system, in particular to an optimal design method for a TMD (Tuned Mass Damper) for installing a spring-mass system. Background technique [0002] As a natural disaster that seriously threatens the safety of human life and property, earthquake has caused huge disasters to human beings. It is one of the many earthquake-prone countries, such as the Wenchuan earthquake, Japan earthquake, and Ya'an earthquake that occurred in recent years. These major earthquakes not only caused great economic losses, but also brought great grief and serious psychological damage to people. In the 21st century, with the rapid development of the world economy, people have put forward higher and higher requirements for the safety and disaster prevention of engineering structures, requiring engineering structures not to be damaged when natural disasters (such as strong earthquakes and typhoons) occur damage...
