摘　　要：某高烈度地区实训基地项目由于建筑方案原因,结构平面和竖向布置不规则,设计指标要求难以达到。通过布置屈曲约束支撑体系改善两个主轴方向的动力特性相差较大问题,通过布置粘滞阻尼器增加结构附加阻尼比,耗散地震能量,使得建筑物的层间位移角满足规范要求。屈曲约束支撑以及粘滞阻尼器在中震、大震时也具有良好的耗能能力,有限保护了主体结构,提高了建筑结构在大震时的安全性,降低了结构总质量,减少了基础造价,满足了建筑使用功能。Because of the irregular structural plane and Vertical Arrangement, the design index of a training base project in a high intensity area is difficult to reach. The dynamic characteristics of the two principal axes are quite different, and the additional damping ratio of the structure is increased by the arrangement of viscous dampers, which dissipates seismic energy. The Angle of displacement between floors of the building can meet the requirements of the code. Buckling-restrained braces and viscous dampers also have good energy dissipation capacity during moderate and large earthquakes, which can protect the main structure, improve the safety of the building structure during large earthquakes, reduce the total quality of the structure and reduce the cost of the foundation. It meets the needs of the building.
