Abstract
With the rapid development of society and the economy, people's life and property safety importance is also more and more high. Especially the occurrence of the Wenchuan earthquake, people on whether the application of civil engineering construction damping scientific and rational approach was questioned. How to ensure the quality of civil engineering construction, to avoid in the event of earthquakes and other natural disasters, the emergence floor crash event, is an issue for all engineering designers and builders focus on. Because of the relationship with all life safety, so how to use rational scientific method damping to the construction of civil engineering structures is very important and necessary. This study from the passive control, active control, semi-active control and hybrid control methods start with four damping research and analysis, combining their research status. The Benchmark problem of structure control has carried on the simple introduction. Focusing on civil engineering structure vibration control method of systematic review, so as to the future of civil engineering structure suspension construction provides the certain reference function
Highlights
INTRODUCTIONA the damage is very large, and it has the characteristics of randomness and sudden, could not accurately predict in advance, so the loss is often caused by very large
T damping control method advocated, which are obtained by taking isolation, energy consumption, external force, reduce the impact caused by the earthquake
External energy is not being involved in the passive control, because it is itself one of passive acceptance
Summary
A the damage is very large, and it has the characteristics of randomness and sudden, could not accurately predict in advance, so the loss is often caused by very large. T damping control method advocated, which are obtained by taking isolation, energy consumption, external force, reduce the impact caused by the earthquake. It is widely used [1]. E ing to whether the role of external forces have can be divided Rinto structural vibration control (1)): passive control engineering structural vibration control active control semi-active control hybrid control base isolation energy dissipation tuned damping (TMD, TLD) active mass damper (AMD) active Control and base isolation active brace system (ABS). Variable stiffness device (AVS) variable damping device(AVD) Variable stiffness variable damping device(AVSD) AMD and TMD AMD and TLD active tendon system(ATS) active control and energy dissipation
