［摘要］将框架倾覆力矩统一解法应用于高层建筑结构体系的判断、0-2V0调整等相关抗震设计的概念中，指出结构抗侧力体系应分水平两主轴方向分别判断、分别设计，且现行规范中0-2V0调整是考虑不足的。对框架倾覆力矩统一解法在不同建筑结构体系中应用的可行性分别予以论证和分析，特别是对框架-剪力墙结构、剪力墙结构及框支剪力墙结构的体系判断和结构设计，相对于抗规法、力学法，框架倾覆力矩统一解法有优势。将框架倾覆力矩统一解法拓展到带斜撑框架的倾覆力矩计算中，使得带伸臂的框架-核心筒结构体系或带巨型斜撑的框架-核心筒结构体系的框架倾覆力矩可以得到准确的计算。

Abstract:The unified calculation method of moment-resisting-frame′s overturning moment (abbrev. MOTM) was applied to the judgment of high-rise building structural system, 0-2V0 adjustment and other related seismic design concepts. It was pointed out that the judgment and design of lateral resistant system should be carried out separately in the two main horizontal directions, and the consideration of the 0-2V0 adjustment in current code was insufficient. The feasibility of the application of the unified calculation method of MOTM in different building structural systems was demonstrated and analysed separately. Especially for the system judgment and structural design of frame-shear wall structure, shear wall structure and frame supported shear wall structure, the unified calculation method of MOTM has advantages over the seismic design code method and mechanical method. The unified calculation method of MOTM is extended to the calculation of overturning moment of frame with diagonal bars, so that the overturning moment of frame-corewall structural system with outriggers or frame-corewall structural system with mega diagonal braces can be accurately calculated.

Keywords:overturning moment; frame structure; frame-shear wall structure; shear wall structure; frame-corewall structure
