[摘要] 消能減震技術(shù)是實(shí)現(xiàn)結(jié)構(gòu)性能化設(shè)計(jì)的有效方法之一，金屬位移型阻尼器具有較好彈性剛度及耗能性能，在消能減震技術(shù)領(lǐng)域被廣泛應(yīng)用。超高層建筑因其高度或體型復(fù)雜往往需要更好的抗震性能，傳統(tǒng)技術(shù)采用構(gòu)件‘硬抗’的辦法，通過(guò)采用消能減震技術(shù)可以保證多遇地震抗震性能水平不改變前提下更有效改善結(jié)構(gòu)抗震性能，設(shè)防烈度及罕遇地震下徹底改變塑性損傷機(jī)制及抗倒塌性能。

Abstract: Energy-dissipated and shock-absorbing technique is one of effective methods for realizing structure performance design, metallic displacement type damper has relatively good elastic rigidity and energy dissipation performance, and it has extensive application in the field of energy-dissipated and shock-absorbing technique. Super high-rise building usually needs better earthquake-resistant capability because of its height or complicated shape, component for "hard resistance" is adopted in traditional technique, by means of adopting energy-dissipated and shock-absorbing technique, the earthquake resistant capability of structure can be guaranteed to be more effectively improved on the prerequisite of unchanged earthquake resistant capability level in frequently occurred earthquake, and the plastic damage mechanism and collapse resistant performance can be thoroughly changed under fortification intensity and rarely occurred earthquake.

Keywords: energy-dissipated and shock-absorbing technique; metallic damper; super high-rise
