摘要
以实际工程为例,对超高层建筑利用避难层设置水平加强层这一措施展开讨论.通过改变外筒环粱高度、水平加强层的位置以及水平加强层的竖向弯曲刚度,进行结构分析,总结在侧向力作用下其内力分布规律,进而对钢筋混凝土筒体结构设置水平加强层所能起的作用进行了探讨,在分析和比较的基础上对高层建筑设置水平加强层的条件提出了一些建议,为今后上程设计提供一些资料.
Based on practical project, using refuge story to set up horizontal strengthened story in supertall building is discussed. The structure is analyzed and its internal force distributing pattern is summarized under the conditions of different outer circline beam height, horizontal strengthened story position and its vertical bending stiffness. Furthermore, the function of horizontal strengthened story in reinforced concrete tube structure is approached. Suggestions for setting up horizontal strengthened story in high-rises are presented on the basis of analysis and comparison, which are reference materials for future project design.
