    Space structures have gained rapid popularity in the past few decades. The structures when properly conceived, designed and fabricated can be elegant, economical and of greater reserved strength than several other conventional structural forms. The structural components are mostly repetitive and hence usually can be mass produced in factories with a high standard of quality control. Several industrialized systems have been developed and successfully applied in the construction industry. The fundamental concepts of their success are usually based on the use of standard components, module elements and efficient connector systems which should be simple for fabrication, convenient for transportation and easy for erection on site. This paper is concerned with behaviour characteristics of simply supported general space structures and the form finding of arch shaped space structure with Mero-joint by post-tensioning. Specially, the arch shaped space structure is assembled initially in a planar layout on the ground and post-tensioned by cables placed inside the short bottom chords. As a results, the top chords become curved and the arch shaped space structure is shaped. Small-scale tests was performed with Mero-jointed space structure in laboratory, and theoretical analysis was performed with three modeling method by finite element in commercial program MIDAS. The author suggests the possibility of shaping formation with Mero-jointed space structure by post-tensioning, and discusses the behaviour characteristics for arch shaped space structure and simply supported general space structure with Mero-joint. However, there is a large discrepancy in the results between experiments and theory for simply supported space structure, it is necessary to study for that structure. Potentially this shaping procedure can be useful to eliminate the need of scaffolding and crane.
