THE IMPLICATION OF HUMAN CENTROID VARIATION DUE TO THE BENDING OVER OF A HUMAN BODY
Keywords:
Safety, Drying rack, Scaffolding, Height restriction of protection barrier, Work at heightAbstract
Work at height is one of the construction activities, and a drying rack is one of the construction products that may need to be considered in the context of construction safety. Both of them involve people standing in a posture with inclining or bending their body out from a stable and safe point toward a place in the air. Conventionally, the construction industry concerns the height of the barrier, the parapet, and the window frame. However, people falling from height can happen when the centroid of the people moves out from the stable point due to the posture of inclining or bending. The study investigates the relationship between the inclining and bending posture of the human body with the variation of centroids and suggests a reference for the inclining and bending limit for designing the gap between the platform and the wall for scaffolding and the size of a drying rack. The reference supporting loadings required for the guard-rail design of scaffolding and the cantilever support design of drying racks are also suggested.References
