Water slides should always be individual. Thereby arrangements of completions are your profession. Afterwards specific verification of stability has to be prepared fast and capable.
Allowing for rigidities of sub-constructions, crucial spots of individual water slides can be shaped by means of the finite element method (fem).
Areas, which cannot be detected adequate, e.g. face plate couplings, were compared to results of tests with building element sections. With this procedure you get safety in spades.
