“…Load-carrying capacity of reticular shell is obviously affected by joint bending stiffness. 5,6 To clarify the influence of joint bending stiffness on limit load of the reticular shell, 11 different magnitudes of joint bending stiffness mentioned in the previous section are considered in this section. In the following numerical analyses, limit load of reticular shell is determined considering both geometrical and material nonlinearity.…”

“…In the past years, lots of efforts have been paid on the investigation of effect of joint bending stiffness on mechanical performance of space structures. Taniguchi et al 5 carried out experimental research on mechanical performance of space trusses, and developed the regression curve of bending moment-rotation relationship of joint system. Saka and Heki 6 researched the influence of joint stiffness on the load-carrying capacity of space truss using a mechanical model with rigid end parts and springs.…”

The main aim of the present article is to study the effect of joint stiffness and joint size on load-carrying capacity of single-layer cylindrical reticular shell. One normalized joint bending stiffness index κb and three proposed normalized indexes, that is, normalized joint axial stiffness κa, normalized joint shear stiffness κs, and normalized joint torsional stiffness κt, are used to evaluate the stiffness of joint. Through a large number of numerical computations, the main conclusions are summarized as follows: κb has a significant effect on limit load of reticular shell, and this effect has a close relationship to rise-to-span ratio of reticular shell. If κb is larger than 30, the joint can be treated as rigid joint. The relationship between the logarithm of κb and limit load of reticular shell can be expressed by the logistic formulation. Overall rigidity and load-carrying capacity of reticular shell are greatly influenced by joint axial stiffness. If κa is larger than 30, the effect of joint axial stiffness on load-carrying capacity of reticular shell is no longer obvious. Otherwise, the load-carrying capacity will be markedly reduced. The relation between the logarithm of κa and limit load of reticular shell can be fitted by the Dose–response formulation. The load-carrying capacity of reticular shell is also influenced by joint torsional stiffness and joint shear stiffness to some extent. The relation between the logarithm of κs and limit load can be fitted by the Asymptotic formulation. The effect of joint size on overall rigidity and limit load of reticular shell is evident and cannot be neglected. The limit load gradually decreases with the decrease in joint size, and there is an approximate linear relationship between limit load and joint size.

“…MERO system or bolted jointing system (Figure 1) was the first patented system for space structures [2]. The buckling behavior was observed in Taniguchi's work [3]. Many other patented systems were also developed but designers have frequently used non-patented systems due to their lower cost compared to patented ones [4].…”

ABSTRACT: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 m 2 were used for laboratory testing. In this paper, for proposal validation, the same research was developed, this time in prototypes with 54 m 2 . 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.
