摘要
基于对连体相对高度系数的定义,变换非对称双塔连体结构的连体相对高度系数,使用结构分析设计系统MIDAS Building对8个算例进行建模分析,并比较不同连体相对高度系数下的该类结构的动力特性,为该类结构的分析与设计提供参考。分析结果表明,连体相对高度系数的变化对非对称双塔连体结构的低阶振型产生较大影响,使结构的自振周期产生显著变化,其总体变化趋势为随着连体相对高度系数的增大而减小。
Based on the definition of connecting relative height （ CRH）, CRH is diverted and structural analyzed and design system MIDAS Building is used to analyze 8 models. With different CRH, dynamic characteristics of the structure are also compared to provide references for analysis and design of the structure. The results show that, changes of CRH have a great impact on both the lower mode and the natural period of asymmetric double - tower adjacent structure. The overall trend is that natural period decreases as CRH enlarges.
