Architecture and structure have always been closely related, but the advent of the steel and reinforced concrete created new needs in the formal aspects. The International Style opted to separate the structural framework from the walls. On the other hand, the Chicago School
forged the basis of a rational and optimized architecture. Between these two situations, Frank Lloyd Wright chose the approach of following the natural patterns of materials, in “organic” manner, recovering the interaction between the different elements of the architecture.

Into the range about the role of the structure in the history of architecture, it seems appropriate to stop the analysis in the work of Frank Lloyd Wright and his particular use of structure. The Guggenheim Museum is the building that reflects many of the constants, so it is worth analyzing its structure. In this sense, the figure of Jaroslav J. Polivka has a particular interest because of his collaboration with Wright. From this relationship sometimes arise the keys, not just the specific solutions for the structure, but the final conditions within the architectural form.
