July 2017 Project:

Rotatable Aluminum Frame Structure for Concert
Rotatable Aluminum Frame Structure for Concert

Hopper Engineering Associates was requested to analyze five identical hanging 10 feet by 10 feet structural frames made out of aluminum. One side is equipped with a display screen while the other has a cantilevered platform for the performer to stand on. The frame is designed to be rotatable and doubles as a lighting platform. The client intends to ascend and descend the platforms from the ceiling using four guy wires for an impressive entry. Due to the unique shape and dynamicity of the platform, multiple loading conditions shall be assessed to ensure its structural capacityand stability to ensure the safety of the performers.


A commercially available structural analysis program was used to model the structural system of the frames. Static and dynamic loads were applied to the model and the member stresses were extracted to ensure structural adequacy. The system was found to be adequate for the applicable loadings.
