[摘要]基于框架倾覆力矩的统一解法,结合工程实践给出3种框剪梁的定义,分别对典型框架-剪力墙结构和框筒结构进行框剪梁可视化识别,并按统一解法计算其框架倾覆力矩占比,与抗规法及目前常用的轴力法进行对比分析。结果表明:统一解法是合理可行的框架倾覆力矩计算方法;只计入剪力墙与框架柱(或斜撑)的框剪梁定义2会显著低估框架倾覆力矩,定义1与定义2结果差异不大,建议采用定义1。同时对框支剪力墙结构框支框架的倾覆力矩进行了举例计算和分析,也验证了统一解法的合理可行。

Abstract:Based on the unified solution method for calculation of moment-resisting-frame′s overturning moment (abbrev. MOTM), three definitions of the frame-shear beam were given with the engineering practice. Visual identification was conducted on frame shear beams of typical frame shear wall structures and frame-corewall structures, and the MOTM′s proportion was calculated by the unified solution method. The method was compared with the seismic design method and the commonly used axial force method respectively. The results show that the unified solution method is reasonable and feasible to calculate the MOTM, and the  definition 2 of frame shear beam which only includes beams between shear wall and column (or brace) will significantly underestimate the MOTM, and definition 1 is recommended because there is little difference between definition 1 and definition 2. At the same time, the overturning moment of the frame-supported shear wall structure was calculated and analyzed with an example, to prove the reasonability and feasibility of the unified solution method.

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