Abstract

Within the discipline of architecture, theory is a parallel discourse which describes the practice and production of architecture and identifies challenges to it especially in its structural composition .
One of the most important theoretical contemporary terms is sublimity .
where the term of aesthetic theory had changed , and sublimity was one of the key concept in nineteenth century and romantic aesthetic .
Following its root in phenomenological and psychological approaches in
which rhetorical effects of the sublime are described in details , which reflect sense glorious , luxuriousness and beauty .
Terminological meaning of sublimity not only refer to this name but
extended to express highness , dread and grandeur . the postmodern notion of sublimity present itself today in several guises including the uncanny , grotesque and the indeterminate . Analysis of previous studies addressing sublimity in architecture has shown
lack of an adequate knowledge concerning the application of sublimity concept in architectural composition . In particular , emphasis was placed upon the nature of sublimity that achieved through different structures , and that what the research problem concentrates on " There was no previous perception about the aesthetic sublime that is accomplished through the structure manipulation in architectural
form " . To achieve this it is necessary to : First phase , formulate conceptual framework composed of two parts ; first , discuss theorists ideas that laid the groundwork for today's emerging aesthetic of contemporary sublimity , and the second , isolate and structure the main and the secondary indicators of sublimity , Second phase , to examine the nature of this indicators on elected architectural
composition that possess a unique structure and finally to determine the final conclusion of the research .
