[22026-31-04] Robust Topology Optimization of Falling Bridge Prevention Brackets Considering Uncertain Acting Loads (Proceedings of Symposium on Applied Mechanics)
Keywords:Topology Optimization, Robust Design, Bridge Fall Prevention Brackets
Bridge fall prevention brackets are designed to resist forces in the direction of the bridge axis.
However, they were damaged by the Kumamoto earthquake in April 2008, and the cause is considered to be the action of forces perpendicular to the bridge axis, which was not assumed in the design.
Therefore, it is necessary for bridges to be robust enough to withstand loads other than the design loads to some extent.
In this study, the optimal structure of a bridge fall prevention bracket under uncertain loading conditions is obtained by a topology optimization method.
