Introduction
This study presents the findings from a comprehensive stability and stress analysis conducted on a planned high scaffolding construction surrounding a 30-meter-high column. The analysis focused on assessing the stability of the column itself and evaluating the local stresses at the bracket connections of the scaffolding, specifically under maximum wind load conditions.
Analysis
The scaffolding is designed in a U-shape around the column, relying on adjacent structures for lateral support necessary to withstand horizontal wind loads. Horizontal forces from the scaffolding are transferred to the column through horizontally arranged connecting tubes.
The impact of wind loads exerted by the scaffolding on the column was carefully examined. This involved two primary aspects:
Global Stability of the Column: A finite element model of the column was subjected to wind loads to assess its stability, particularly under maximum wind load conditions. Buckling analysis was employed to verify the column’s global stability.
Local Stresses on the Brackets: Detailed analysis focused on the brackets supporting the platforms around the column under wind conditions. This study evaluated the local stresses within the column’s shell near the brackets and within the brackets themselves. The analysis assumed operational conditions of the column without additional loads from people, tools, or other sources on the platforms during maximum wind load scenarios.
Results
The results of the global stability analysis confirmed that the column maintained sufficient stability under wind loading conditions, with a significant safety margin. The stress analysis of the brackets indicated adequate performance, though with a slightly narrower margin compared to the global stability assessment.
Conclusions
The stability and stress analysis of the scaffolding project underscored the importance of evaluating structural integrity under wind load conditions. The study concluded that the column and its bracket connections were adequately designed to withstand maximum wind loads, ensuring the safety and reliability of the scaffolding construction.
