摘　　要：文章介绍了一种组合式消能减震技术在某医疗建筑中的应用,该组合式消能减震技术选用位移型的屈曲约束支撑和速度型黏滞阻尼器,将两种不同类型的技术产品组合,既可以给建筑提供有效的抗侧刚度,又能实现较大的附加阻尼比,可满足医疗建筑设防地震正常使用的要求。对某医疗建筑进行组合式减震分析,结果表明,在罕遇地震下,组合式减震可充分利用金属材料的弹塑性和黏滞滞回变形耗散和吸收地震能量,有效降低结构的地震响应,提高建筑的抗震安全储备水平。This paper introduces the application of a combined energy dissipation and seismic reduction technology in a certain medical building.The combined energy dissipation and seismic reduction technology uses displacement type buckling constraint support and velocity type viscous damper.By combining two different types of technical products,it can provide effective lateral stiffness to the building and achieve a large additional damping ratio,which can meet the requirements of earthquake resistance and normal use of medical buildings.A combined seismic reduction analysis was conducted on a medical building,and the results showed that under rare earthquakes,the combined seismic reduction can fully utilize the elastic-plastic and viscous hysteresis deformation of metal materials to dissipate and absorb seismic energy,to effectively reduce the seismic response of the structure,and to improve the seismic safety storage of the building.
