Abstract | Deployable shelters of various forms have been utilized since ancient civilization. The need for these systems has not diminished over time and development continues The current study is the first to investigate a suitable truss system for the M2S2 concept. Accordingly, it was necessary to validate the M2S2 concept by searching the An innovative all-composite truss concept, named Multi-Pultrusion Truss-System (MPTS), was developed as a result of this study. It overcame the classical difficulty Two MPTS alternatives were developed, tested and investigated. The first alternative used a Discrete-Diagonal (DD) bracing system made of sandwich The second alternative used a Diaphragm (DI) bracing system. Three different DI-MPTS panels were investigated. The first panel had an empty diaphragm (no core); the second panel had a partially-filled sandwich diaphragm while the third panel had a completely-filled sandwich diaphragm. To achieve understanding of the basic behaviour of each of these panels, finite element (FE) analyses were conducted at micro level. The different components of Due to the associated costs of micro-model analyses, macro-analysis models are important tools for engineers interested in modelling this system, conduct pre-microanalysis parametric studies and in modelling the overall frame structure. This study ended with presenting simplified analysis procedures for the different panel types. The work conducted in this study has revealed that this new fibre composite truss system suits the characteristics of fibre composites and accordingly provides an |
