［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。

Abstract: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.

Keywords:buckling-restrained brace; shear damper; energy dissipation system; periodic rationality; elastic-plastic time-history analysis
