摘要:
为了正确定义短肢剪力墙,用肢强系数ζ和整体性系数α来反映短肢剪力墙的受力特性.通过弹性有限元方法对联肢剪力墙在水平力作用下顶点水平位移的分析研究,发现了联肢剪力墙的顶点水平位移随肢强系数ζ的变化规律.当ζ<k[ζ]时,水平位移曲线比较平缓,[ζ]为区分剪力墙和框架的肢强系数限值,k为与楼层数有关的系数.由此,把联肢剪力墙分为2段,满足ζ<k[ζ]的为长肢联肢墙,ζ≥k[ζ]的为短肢联肢墙.同时还指出我国《高层建筑混凝土结构技术规程》(JGJ3—2002)给出的短肢剪力墙的定义只考虑墙肢截面高度,不考虑洞口大小,因此是错误的.
Abstract:
To correctly define short-limb shear wall, the limb strength coefficient ζ and the integrative coefficient α are used to exhibit the mechanical performance of short-limb shear walls. Based on the analysis on top displacement of combined shear walls subjected to top horizontal loading by elastic finite element method,the law of top displacement of combined shear walls due to the varying of the limb strength coefficient ζ is acquired. The curve of top displacement is gentle when ζ is less than [ζ], here [ζ] is the limited value for distinguishing shear wall and framework,and k is a coefficient related to the number of stories.Therefore combined shear walls are divided into two classifications, i.e. short-limb shear walls satisfying the condition ζ greater than or equal to k[ζ] and long-limb shear walls satisfying the condition ζ less than k[ζ]. Meanwhile, it is pointed out that the definition of short-limb shear walls given by Chinese code ‘Technical specification for concrete structures of tall building’(JGJ3—2002)is wrong because the definition only considers the height of section of limb without taking the opening into account.
