In the first stage of this research the proposal of the reinforced node used in space truss was presented. Computer simulations and experimental lab tests were performed with small changes on the staking flattened-end connections, such as reinforcement and eccentricity correction. The results showed 68% increase in the truss load carrying capacity when the proposed changes were applied. However, small prototypes measuring 4 m2 were used for laboratory testing. In this paper, for proposal validation, the same research was developed, this time in prototypes with 54 m2. The outcome results of this research, confirmed a significant increase in the truss load carrying capacity. It is expected that factories can apply the reinforced node in space truss constructions to come.
