By carrying out a strength calculation, we provide the "manually calculated" proof of how much a structure or a component is loaded or deformed. This method is suitable for the design and strength calculation of relatively simple components (eg machine elements, supports, etc.). The study of complex structures / components or statically indeterminate systems must then be done by finite element method (FE analysis).
For the design and calculation of prestressed bolted connections, this is also the case for testing and securing.
The following standards and regulations serve as the basis for the strength analysis and strength proofs:
