  Abstract

This study analyzes the validity of the design allowable compressive stress suggested in the design standards of the new material vertical members in system scaffolds and system supports through experiments. The experimental results were compared with the design allowable compressive stress presented in the design standards for steel structure members (KDS 14 30 10), steel bridge design standards (KDS 24 14 30), and road bridge design standards. As a result of comparing the design formula and the experimental results for the vertical members of the system scaffold, experimental results were found to be similar to the design allowable compressive stress calculated from the road bridge design standard. For the vertical members of the system support, the experimental maximum compressive stress considering the safety factor in all specimens was smaller than the allowable compressive stress suggested in the design criteria. The case, in which the difference between the experimental value and the design standard allowable compressive stress is the smallest is the steel bridge design standard. As the slenderness ratio is relatively large, the difference between the experimental value and the design allowable compressive stress was significant.
