本文根据双肢剪力墙连续连杆法的基本假定,讨论了双肢墙计算图与实际结构间的差异。从力法典型方程出发,计算、分析了双肢墙从实际上分层而设的连粱到连续分布的连杆的简化所带来的误差。并根据高层规范对水平位移的限制,用模糊数学的方法定义了工程实践中剪力墙结构总层数的“多”与“少”,给出了计算误差“大”与“小”的数值含义,从而明确了连续化方法的适用范围,确定了建筑总层数与计算误差间的模糊关系,便于实际应用。 In this paper, based on the basic assumptions of the continuous linkage method for the double-limb shear wall, the differences between the calculated diagram and the actual structure of the two-limb wall are discussed. Starting from the typical equation of force method, the error caused by the simplification of the double-limbed wall from the actually layered connection to the continuously distributed connecting rod is calculated and analyzed. According to the high-level specification of the horizontal displacement limitation, the “multiple” and “less” of the total number of shear wall structures in the engineering practice are defined by means of fuzzy mathematics, and the numerical values ​​“large” and “small” are given. Meanings, thus clarifying the scope of application of the continuous method, and determining the fuzzy relationship between the total number of buildings and the calculation error, which is convenient for practical application.
