Structure is an essential part of any piece of architecture. Frankly, it's a reason why buildings don't collapse. Whether it is a house, a bridge or a stadium, it is subject to a series of loads that must be resisted in one way or another. The structures are intended to transfer loads from the points where they are applied to the foundations. No building can exist without this component and very often architecture is defined by structures and not vice versa. In any case, it must certainly be a point of high consideration by both architects and structural engineers. Biological structures have existed long before man-made structures, not to mention structures in architecture. If you think about it, almost every specimen of flora and fauna has a structure to resist mechanical forces in order to prevent breakage. The human body has a structure: a skeleton combined with muscles and skin provides humans with stability allowing us to stand but also flexibility allowing us to move, it also provides our internal organs with adequate shelter so they can function properly. The structure of a human body is indeed complex almost beyond comprehension, the structure of any man-made structure, on the other hand, the structure of the buildings examined in this particular essay can and should be understood at least by anyone who participates in the project process of designing anything to do with buildings. The simplest way to visualize the role of a structure is to imagine a typical house as a container that hides and provides shelter for its contents. Each wall of that container is subjected to a series of loads of various kinds: the own weight of the building, the imp...... .In summary, structures are inevitable and, like it or not, an architect must understand clearly their purpose, as well as the principles by which they are governed. Of course, meeting the requirements that the laws of physics apply to every object on Earth puts us in a certain freedom-limiting framework. Of course, buildings designed in a vacuum without the constraints of all the acting forces would be much more interesting and would allow greater freedom in expressing ideas. However, building without the need for a structure would eliminate the factor of the challenge of blending functionality and aesthetics, which is perhaps one of the main reasons why architecture is an art form. Yes, the structural part of buildings can represent a huge limit but, on the other hand, it transforms good modern architects into great architects.
