Occasionally a need arises to retrospectively certify existing structures or equipment. This may be due to end client requirements or changes to structures. As a result load rating needs to be determined and the equipment certified. In conjunction with our client, we can certify the equipment in just a couple of steps. Following are the procedure steps in broad terms:
- Measure up existing structure or model from drawings
- Determine grade of materials of construction
- Model in 3D or use SPACE GASS structural analysis
- Apply loads and load cases in accordance with the relevant Australian Standard. Latest versions of the Australians can be purchased here.
- Iteratively calculate the load that would lead to compliance with the standards
- Record load rating in a calculation report
- Perform actual load testing if required
- Provide nameplate/marking of structure.
All of the above work is done in compliance with the Australian Standards. This ensures that the equipment and structures are safe and strong enough for many years of utilisation. For example Dynamic Engineering has applied this process to monorail structures, maintenance stands, jib cranes, platforms, winches etc.
Another example is a fabricated welding rotating jig is shown above. The picture below shows the 3D model, ready to be analysed with Finite Element Analysis by applying loads and constraints to find the highest stresses and deflections.
