基于高层建筑短肢剪力墙结构肢高比设计

The Design of the Scale of Width and Height for Shot-pier Shear Wall Structure in High-rise Buildings

短肢剪力墙结构是一种新型抗侧力结构体系,被广泛用于高层及超高层民用建筑中。针对《高层建筑混凝土结构技术规程》(JGJ3—2002)短肢剪力墙定义叙述的不足之处,通过有限元法对154片肢墙系数α及整体性系数ζ各不相同的8层、10层、12层对称双肢剪力墙按1/7缩尺比例进行了弹性分析,按只在少数楼层出现反弯点的要求,对三种楼层分别施加水平均布荷载和水平倒三角形分布荷载进行低周反复试验。规范了高层建筑短肢剪力墙结构的定义,明确了剪力墙结构肢高比设计的选取范围。

The structure of shot-pier shear wall is a new mode lateral resistant system which is widespread used in high-rise buildings and mega-high-rise buildings. The article elastic analysis 8 floor, 10 floor and 12 floor which are quite different from each other through 154 pieces coupled wall coefficient c~ and integritycoefficient coefficient ~＂ in accordance with the definition accordance within accordance within accordance with coefficientcoefficienttechnical specification for concrete structures of tall building （JGJ3--2002）narrated. On the basis of request of emerging point ofcontra flexure in a few floors, the article used the trial and error method toimpose impose the horizontal uniforrrdy distributed load and horizontal del operator uniformly distributed. The article standardized the definition of structure of shot-pier shear wall of high-rise buildings and clarified the boundary of width and height scale ofshearwall structure, impose .
