摘　　要：以成都市某教学实验楼为例,对其进行了基于黏滞阻尼器(VFD)减震技术的抗震性能提升设计,并采用PKPM-JZ和SAUSG软件进行了多遇地震和罕遇地震荷载作用下结构的弹塑性动力分析。时程分析结果显示,设防地震和罕遇地震作用下,此建筑各向弹塑性层间位移角均达到特定的减震目标;该建筑的结构各项指标均满足了相关规范要求,达到了设计的预期目标。通过这些措施,该建筑在地震发生时能够有效减少震害,保障师生的生命和财产安全。According to the rule of anti-earthquake for structure,vibration-reduction technique has to be used in new-built school to assure its reliability under specific earthquake.Take a laboratory building for teaching in Chengdu for example,based on viscous damper,anti-earthquake enhancement design is used.PKPM-JZ and SAUSG is used to conduct this structure’s elastoplasticity dynamic analysis from frequent earthquake to rare earthquake.Results show that interlayer displacement angle of different direction can meet the expecting vibration-reduction goal under specific and rare earthquake.Each structural index of this building can meet the request in relative specification and reach the expecting design goal.This building can efficiently reduce the harm of earthquake and assure the safety of life and property of the school teachers and students.
