摘　　要：针对高烈度地区重荷载、高层高、大跨度的物流类型的高层建筑,对比框架、框架-剪力墙及框架＋消能减震结构体系这三种结构体系方案的小震分析结果,并且研究了采用屈曲约束支撑（BRB）和支撑式剪切型阻尼器（MD）的混合使用方式（BRB＋MD）的框架体系的周期合理性。通过大震弹塑性时程分析,验证了框架＋消能减震结构体系的抗震性能。结果表明,在高烈度地区框架＋消能减震结构体系是这种类型建筑可采用的合理抗震体系。For the high-rise logistics buildings with heavy load, high storey height and long-span in high intensity region, the results of small earthquake analysis of three structural systems： frame, frame-shear and frame＋energy dissipation structure system were compared. The periodic rationality of BRB＋MD frame system, which uses both buckling-restrained brace（BRB） and supported shear damper（MD） was demonstrated. Through the elastic-plastic time-history analysis under the rare earthquake, the seismic performance of frame＋energy dissipation structure system was also verified. The results show that the frame＋energy dissipation structure system is a reasonable seismic system for this building type in high intensity region.
