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.
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.
