Research On Layout Of Control-MTMD And Seismic Time-history Analysis Of High-rise Building

With the development of city, more and more skyscrapers emerge out in a large amount; this relieves the land tense problem in the city greatly. However, because our country is in the country where earthquake occurs frequently. the following security question arouses the attention from people gradually. Reducing the structure of the building's response under the earthquake driving becomes current extremely important research topic. The passive control as one kind of the structure vibration controls because its merit has widespread application in domestic and foreign. At present the related MTMD ant vibration theory is also mature day by day, but it aims at the research on how to reduce the breeze inspires. Therefore, this article has conducted the research to the high-rise construction MTMD absorption of shock.This article through establishment structure - TMD, the structure - MTMD computation model, has derived the structure quality, the rigidity and the damping matrix, and inferred the quality, the spring rigidity and damping equation of each TMD by TMD and the structure relations. In the TMD arrangement aspect, proposed four kind of different schemes of arrangement, and confirmed the influence when arrange TMD as well as MTMD to the construction through the example by using the time-history analysis method in high-rise building. The result indicated that, under the different earthquake wave action, the TMD control effect also has the difference; There is also influence on the structure absorption of shock when the TMD arrangement in the different position. Its result will have certain reference value to the actual application in the project of afterwards.
