2. THE EMERGENCE AND DEVELOPMENT OF FOLDED STRUCTURES IN CIVIL ENGINEERING
Design and construction of folded structures occurs at the beginning of the twentieth
century, and is associated with the development of reinforced concrete [13]. The basic
idea of creating this type of construction is striving to achieve more constructive height
and greater rigidity and reduce the net weight of the structural element. The strength and
stiffness of folded construction is achieved primarily by proper design of the structure,
and to a lesser extent, by thickness and dimension of the elements that form it. This solution
was possible to realize due to the development of structural systems and the use of
reinforced concrete.
Engineer Eudene Freyssinet performed the first roof with the folded structure in 1923
as an aircraft hangar at Orly Airport in Paris. In technological terms this folded construction
is made of prefabricated elements, with pre-stressed structure, which is a remarkable
engineering undertaking of the time [16]. Based on the application of this pre-stressed
structure Eudene Freyssinet has been called "the father of pre-stressed concrete.
Folded structures have emerged as a counterbalance to heavy frame structures, in which
the net weight is very great and that are cost-effective only for ranges up to 25 m [12]
