[摘要] 消能减震技术是实现结构性能化设计的有效方法之一，金属位移型阻尼器具有较好弹性刚度及耗能性能，在消能减震技术领域被广泛应用。超高层建筑因其高度或体型复杂往往需要更好的抗震性能，传统技术采用构件‘硬抗’的办法，通过采用消能减震技术可以保证多遇地震抗震性能水平不改变前提下更有效改善结构抗震性能，设防烈度及罕遇地震下彻底改变塑性损伤机制及抗倒塌性能。

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
