Purpose: This study verified the behavior of a temporary structure module system for preventing overturning drilling rigs by comparing the efficiency of the mechanical mechanism with the results of a numerical analysis method and load test of a full-scale specimen. Method: The geometric and material specifications of existing a temporary structure were analyzed and the specifications of temporary structure module system of this study were derived. Numerical analysis was performed by applying the total load and impact force of construction equipment, and static loading experiments of a full-scale test specimen using horizontal and vertical loading method was performed. Result: The results of static loading experiments of the full-scale specimen showed that the vertical displacement in response to the applied load exceeded the results of the numerical analysis. It was confirmed that the vertical member with the most unfavorable behavior was subjected to a nominal stress of 81.6 to 82.3% of the allowable stress. Conclusion: The safety of the behavior was confirmed through a comparative result of numerical analysis and static loading experiments on a full-scale specimen for a temporary structure module system for preventing construction equipment from overturning that applies a mechanical mechanism in which the overturning moment of construction equipment and the resistant moment due to the self-weight of equipment complement each other.
