摘　　要：框架摇摆墙结构依据框架与摇摆墙连接构件的连接属性可以将其分为框架摇摆墙刚接体系和框架摇摆墙铰接体系。为了进一步提高框架摇摆墙结构的工程实用性,本文依据连续化假设及协同工作原理提出了框架摇摆墙铰接体系和框架摇摆墙刚接体系的内力和位移的简化计算方法,以利于框架摇摆墙结构在初步设计阶段的设计分析,并比较了在摇摆墙截面不同情况下结构的内力分布和位移分布。结果表明,框架摇摆墙铰接体系的顶点位移不随摇摆墙刚度的改变而改变,摇摆墙的作用只是平均各层的层间变形,而刚接体系的顶点位移与摇摆墙的刚度有关,刚接连梁的存在可以增加结构的刚度。Frame rocking-wall structure can be divided into pined connection system and rigid connection system according to the connection properties of framework and rocking wall connection components.In order to improve the engineering practicability of frame rocking-wall structure and to facilitate the design of frame rocking-wall structure analysis in the preliminary design stage,a simplified method of internal force and displacement of pined connection system and rigid connection system is presented according to continuous assumption and cooperative work principle.And the internal force and displacement distribution under the condition of the difference wall section are compared.The results show that the displacement of the vertex of pined connection system doesn＇ t change with the stiffness of the wall.The role of the wall makes the interlayer deformation of structure on average,but the displacement of the vertex of rigid connection system is related to thestiffness of rocking-wall.
