Post-Tensioned Modular Inflated Structures 233 6 Examples of Application Modular inflated shells are suitable for wide range of applications.Some exam- ples given below are aimed to emphasize general concepts rather then describe particular implementations.These shells can be successfully combined with many other well-known types of structures. 6.1 Cylindrical Shells The simplest possible shape of modular air-inflated shell is a cylinder.This can be used directly for some applications,or as a part of a bigger,complex structure.However,even in this case,structure can be constructed in various ways.This can be composed only of cushions and cables,Fig.17,or with optional use of cross-braces,Fig.18 and Fig.19. Fig.17.A simple cylindrical shell composed only of cushions and cables Cross-braces can be placed inside the structure or in reverse position,over cushions,in order to enlarge internal space,Fig.18. For a specific architectural effect,semi-rigid cushions are very promising. The external rigid panel can be made of translucent or painted plastic and some printed patterns can be added,Fig.19. 6.2 Construction Site Shelter In many cases,the construction site should be prevented from the weather conditions.It concerns,for example,concrete works as well as earth works. An exemplary structure is presented on Fig.20.It consists of the three simple cylindrical shells that form a shelter over rectangular area.Exactly the same structure is suitable for sport facilities,e.g.tennis court.Post-Tensioned Modular Inflated Structures 233 6 Examples of Application Modular inflated shells are suitable for wide range of applications.
