带加强层框—筒结构侧移的子结构叠加分析方法
|
摘要
随着经济的发展,城市土地资源越来越紧张,高层建筑在现代城市建设中得到了广泛的发展和应用。当建筑高度增大时,结构的受力特征也逐渐受竖向荷载控制转变为受水平向荷载控制。框架—核心筒结构作为高层建筑经常采用的结构体系,在水平荷载作用下,常因抗侧刚度不足产生过大的侧向变形。在框架—核心筒结构中设置水平加强层,能利用外框架柱的轴向拉压作用,提高整体抗侧刚度,减小结构侧移。本文对设置多道加强层框—筒结构,在水平静荷载下的侧移,构件刚度匹配及结构优化等方面进行了分析。
论文首先介绍了高层框架—核心筒结构中,设置加强层的作用机理、静力分析理论,以及顶部设置加强层子结构的侧移分析模型和计算方法。进而采用叠加法,化整为零,将设置多道加强层结构拆分成多个顶部设置加强层的子结构进行侧移分析,并考虑了上部结构约束作用的影响,对叠加法加以完善和修正。之后,对一个设置0～4道加强层的简化框—筒结构算例进行了侧移计算,并对结果进行了分析。
论文还结合算例,分析了加强层刚度、楼层梁刚度和外框柱刚度变化对结构侧移的影响,在此基础上,讨论了加强层设置的规律和构件刚度选择的范围,提出了一些结构优化设计的概念、方法和原则。
As the development of economy, more and more scarcity of land resources causes the widely application of the high-rise buildings in the constructions of modern city. With increasing height of building, the mechanics characteristic of structure controlled by vertical lateral force gradually became that lateral controlled by force. As a structural system frequently used in high-rise buildings, Frame-tube Structure was induced in excessive drifts because of the deficiency of the transversal stiffness under the lateral forces. Utilizing axial tension and compress in external frame columns, Frame-Core Wall Structure with transversal strengthened story could be improved in integral lateral rigidity, and the displacement of the structure was reduced. The analysis in this paper was focused on the side displacement of transversal static load, element’s stiffness matching, optimized design in Frame-Core Wall Structure with several strengthened stories. This paper sets forth the mechanism and static analysis theory of strengthened story, in high-rise Frame-Core Wall Structure, as well as analytic model, calculation method of sideway in the sub-structure with strengthened story applied in the top of the structure.
Then the superposition method was introduced in sideway analysis to decompose the structure with several strengthened stories into several corresponding sub-structures discussed above. The influence of the confined effect of upper structure was taken into account to improve and modify the superposition. After that, an example, simplified Frame-Core Wall Structure with different number, say 0~4, of strengthened stories, was given to show the calculation of sideway, then the analysis of the results was followed.
This paper incorporated an example to analysis the influences of the variation of stiffness of the strengthened story, the floor beam and the frame columns in lateral displacement of the structure. According to that, this paper also discussed the regularity of setting strengthened story and the range of the selection of the component’s stiffness, and made a conclusion referred to the concept, methodology, principle of the optimized design of the structure.
