摘要

以承受定常和周期风载的高层建筑为背景

研究外观形体比例对于结构物横向振动响应的影响规律.将矩形截面的高层结构物抽象为一Euler悬臂梁结构

通过分析其本构关系建立动力学模型

采用Galerkin原理及振动理论得到结构的振动响应

研究表明外观形体比例对高层结构在顺风向载荷作用下的振动有重要影响:在定常载荷作用下

结构物的顺风向位移随高层结构物的迎风面高宽比增大而增大;而在周期激励载荷作用下

结构物发生顺风向振动

结构的最大顺风向位移对结构物的外观形体比例敏感

却并不单调变化.

Abstract

The effects of body shape proportions on the horizontal vibration of high-rise buildings under constant wind loads and periodic ones were investigated

respectively. A typical building with a rectangular section was considered as an Euler cantilever structure. By analyzing the constitutive relation

its mechanical model was made. Then the vibrating response of the structure was derived by employing the Galerkin principle and vibration theory. It was found that the body shape proportion was of great importance to the vibration of the high-rise buildings under downwind loads. Under a steady air loading

the maximal displacement in downwind direction would be larger if the proportion between the height of the building and the width of its windward side was bigger. However

under a periodic wind load

the vibration of the structure in downwind direction would occur where the horizontal vibrating response of the high-rise building was sensitive but not monotonic to the variation of the body shape proportions. The investigation had some potential application value in the shape design of high-rise buildings.
