| 摘 要： | 多层与高层框架在侧力作用下的侧向变形,国内外的各资材中,都认为是“剪切型”的,或谓以“剪切型”变形为主,因而高层框架可用等效剪切梁代替之。作者认为这种说法并不正确,因高层框架的侧向变形,能与梁的剪切变形可比拟的部分,即剪切型变形的量值仅占整个变形的一小部份,而主要的还要“弯曲型”变形。此外,本文认为各资料提出的高层框一剪体系框架与剪力墙之间的相互作用力的大小与变化规律的说法亦是不妥当的。

| Abstract: | In all information at home and abroad, the lateral deformations of multistorey and high-rise frame under the action of lateral forces are considered to be "shear mode" or in orther words the dominant deformation is "shear mode". For this reason the multistorey and high-rise frame may be replaced by an equivalent shear beam in the analysis. However, according to the view of author, it is an incorrect statement, because the proportion of "shear mode" deformation in the whole of laternal deformation of multistorey and high-rise frame is very small in comparison with the "bending mode" deformation. In addition, the author believes it is also unreasonable to present the magnitude and the varying pattern of the interaction forces between the frames and shear wails in the multistorey and high-rise frame-shear structure system. |
