Abstract

In this study, a hypothetical tall building structure consisting of two towers and a common podium is analyzed considering effects of interaction between the towers due to connected podium floors. Interaction effects on the podium level are included in the analyses by embracing either an upper bound or lower bound approach, assigning fixed or free end restraints at the continuous boundaries of single tower models, respectively. Response of single tower models are then compared with the response obtained from combined model which includes both of the towers as well as the common podium and basements. Obtained results indicate that, in both linear and nonlinear analyses, single tower models with fixed end restraints overestimate internal forces at the podium floors, although to a reasonable extent.

同一平台上多塔的地震反应分析:典型案例研究

在这项研究中，分析了一个由两座塔楼和一个公共裙楼组成的假设高层建筑结构，考虑了裙楼楼层连接引起的塔楼之间相互作用的影响。通过采用上限或下限方法，分别在单塔模型的连续边界处分配固定端或自由端约束，分析中包括了对裙楼水平的相互作用影响。然后将单塔模型的响应与组合模型获得的响应进行比较，组合模型包括两个塔以及公共裙楼和地下室。所得结果表明，在线性和非线性分析中，带有固定端约束的单塔模型高估了裙楼楼层的内力，尽管在合理的程度上。

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
