Some issues on the design and analysis of pneumatic structures
Pneumatic structures are the tensile structures par excellence, since only with them it is possible to have all elements working in tension. This paper describes the evolution of pneumatic structures, as well as several issues related to its design, such as different pattering methods, the distinctions between high and low energy systems, and whether large strain material models, pressure variations or cable sliding are required to proper design. Selected civil engineering applications, designed by means of simple numerical models, are also presented.
