摘　　要：在竖向荷载作用下,框架和砌体剪力墙共同承担竖向荷载,通过有限元模拟分析了梁截面高度、柱截面高度、砌体墙高度对竖向均布力作用下单跨两层混合结构的框、墙协同工作性能的影响。结果表明影响二层柱轴力分配系数的最显著因素是砌体墙跨度和柱截面高度,两者的变化都在7%左右。Under the vertical load,RC framing and the masonry shear wall bear the vertical load together.In this paper,the influence of beam section height,column section height and masonry wall height on the frame and wall cooperative performance of the single-span two-story mixed structure under vertical uniform force is analyzed by finite element simulation.The results show that the most significant factors affecting the axial force distribution coefficient of the two-story column are the span of the masonry wall and the height of the column section,both of which are about 7%change.

关 键 词：砌体剪力墙 梁截面高度 柱截面高度 协同工作
