摘　　要：近年来消能减震技术在结构中的应用越来越多,铅剪切型阻尼器作为一种构造简单、耗能效率高的位移型阻尼器在消能减震结构中有广泛应用。本文结合《高层混凝土结构技术规程》(JGJ 3—2010)和美国联邦紧急事务管理局颁布的FEMA356标准中的相关规定,对某高层剪力墙结构进行罕遇地震下的抗震性能分析,考察在设防烈度为8度(0.3g)下设计的结构通过安装铅剪切型阻尼器能否经受9度罕遇地震的考验,同时给出了减震前后结构在9度罕遇地震下的性能水准。In recent year energy dissipation techniques are more and more applied in the structures. Lead shear dampers as a simple and highly efficient displacement type of energy consumption dampers have been widely applied in the energy-dissipated buildings. Seismic performance of a high-rise shear wall building were analyzed under the severe earthquake using'Technical specification for concrete structures of tall building( JGJ 3—2010) 'and'FEMA356'which is issued by the U. S. Federal Emergency Management Agency to inspect whether the damped building can stand up to the test the earthquake with the fortification intensity of nine,which is designed under the fortification intensity of eight, meanwhile the seismic performance will be given before and after the structure is damped.
