Development of Modular Deployable Composite Shelters

Australian Structural Engineering Conference 2005

Abstract: The need for deployable structures has existed since ancient ages for example, tent structures have been used in different places around the world. Deployable shelters are needed for military applications, aid relief temporary and/or remote structures. Deployable structures are similar to normal structures in that they are stable and can carry designated loads in their deployed status. In addition, they should satisfy the deployability requirements of being able to be dismantled, stored and transported in a compact form. Deployable structures should also have an inherent deploying mechanism that allows the transmission between the deployed status and the dismantled status and vice versa. The design and capacity of deployable structures was limited by contemporary available materials, methods of construction, and the transportation capacity. In the 1980's, Strarch developed a post-tensioned steel building frame system that has since been applied to many large structures around the world. The system incorporates prefabricated truss frames that are flat in the assembled position with all services and cladding fixed. The frames are erected in their final arched position by a post-tensioning stressing procedure with cables passing through the bottom chord (Strarch, 2001). A research programme was developed to extend the existing Strarch concept by developing a system with dramatically improved deployment characteristics. There was early recognition that the use of fibre composite materials in this system would probably be necessary. This paper provides a review of developments in deployable shelter technology, followed by a review of key performance and design criteria. The development of structural concepts to meet these criteria is then discussed.
