The Interstitial in Structural System in Architecture

Previous knowledge has shown a concept revealing different boundaries and relations of building spaces with its outer shell; which represent the boundaries of these spaces. This concept is called interstitial space which is based on creating an interlocution and communication within this space giving a new understanding of meaning and a new approach in archi-tectural formation. This concept of knowledge description has varied as it is linked once to its nature or again to the built environment levels whether it's architectural or urban diverged within the academic and social context, as well as the blur-ring relationship nature of this space with the structural system of the building. Therefore, the problem state of this research, which goal focuses on, is highlighted as "the urge to investigate the concept of interstitial structure characteristics". Yet the methodology of the research is based on the descriptive and analytical approach consisting of three phases; phases one is to build a theoretical framework about the characteristics of the interstitial space in architecture; second is to conduct a practical study and identify several samples of buildings vary in their structural systems (traditional, structural and space); then analyze data and identify the conclusions of which the interstitial space grows and expands physically and expres-sively with the presence of the recent constructive systems and the lack of presence of the Interstitial spaced has led to spatial differentiation and closed toward inside especially those designed parametrically and reflect it in the other tradi-tional and structural constructive systems.
