Omar, T. and Van Erp, G. and Aravinthan, T. and Key, P. (2008) M2S2 modular deployable shelter system: concept and analysis technique. In: ISEC 4: Innovations in Structural Engineering and Construction, 26-28 Sep 2007, Melbourne, Australia.
Deployable shelters of various forms have been utilized since ancient civilization. The need for these systems has not diminished over time, and development continues for military forces, civilian humanitarian aid, and post- natural disaster scenarios. Recent developments have focused mainly on tent type structures, air beam technology and steel frames supporting soft fabric, yet none of these have fully satisfied the deployability requirements. The Military Modular Shelter System (M2S2) initiative is a research project that aims to develop a fiber composite re- eployable arched shelter system with rigid PVC or fabric cladding. The main frames are formed from modular fiber composite panels that are connected and stressed in position by prestressing cables. Using prestressing as a deploying mechanism, applying loads at the erection and assem-bled stages and changing of the support boundary conditions necessitates the inclusion of the erection process in the frame analysis. This paper presents the concept of M2S2 followed by a brief description of the applied loads. Three analyses procedures, two linear and one non-linear, are used to locate differences in predicting the behavior of the frames. The analyses comparison shows that modeling the erection process along with ap-plying loads relevant to each deploying stage by nonlinear analysis is essential for this type of structures.
