Abstract
This research focuses on the structural analysis and modelling of system scaffolds during construction. The study indicates that the critical load of a system scaffolds unfastened by inner diagonal braces is close to that of a modular steel scaffold. The joint stiffness among vertical posts in the system scaffolds can be defined based on the comparison between analytical and experimental results. The critical loads of system scaffolds reduce while the scaffold stories increase. The inner diagonal braces evidently increase the critical loads of the system scaffolds. The coupling joint positions among vertical posts are supposed to be kept away from the story-to-story joints to prevent a reduction in critical loads of system scaffolds. When the quantity of the extended vertical posts at the bottom of a system scaffold structure increases, the critical load of the system scaffold structure decreases. An example of a large Christmas tree setup by system scaffolds is analyzed in this study.
