Enhancing Structure Expression And Aesthetic Aspect Using Perforated Shear Wall Panels In High Rise Building Facade

This study is oriented to and is part of the research on possible methods towards enhancing the integration of aesthetic and rational co-design process. More specifically, in this study will be addressed the structural systems that do have the potential to enrich the aesthetic vocabulary and visual character of tall buildings through using perforated shear wall panels. The purpose of this study coincides with the research in revealing structural behavior and the potential criterion for judging the aesthetic value of a structure. There have been also clear statements made by different authors about several structures which have been considered artful, as well as rational and efficient, and also being admired for their aesthetic qualities. The aim is to give a referee approach that can exhibit shear wall elements putting on façade of tall buildings not only as rational features, but as important visual components that afford opportunities for creative expression. The initial hypothesis raised in this text is that perforated shear wall panels behave very much close to shear wall elements without openings. So, this study aim to present a considerable interest for numerical investigation of seismic response of perforated shear walls panels taking into account several openings.The following methodology divides this study in two main parts: the first is dedicated to several case studies quite interesting for perforated concrete exterior shell used in high rise buildings such as O-14 Tower Dubai – design by RUR Architecture, COR Building in Miami by Oppenheim Architecture and Mikimoto Ginza 2 in Tokyo with different arrangements of openings in the concrete shell façade of the buildings which do confirm a better understanding with regard to the performance of shear walls/shell elements in this study in terms of perforated shear wall; the second is by modeling different 2- dimensional elevation perforated shear walls analyzed by ETABS program. The investigated case studies and the models will lead to a verification of the initial hypothesis, which results will be presented in the paragraph of the conclusions.
