Question

In the case of the serviceability limit state design (for example, of a steel beam), the precamber is not taken into account. Is this a program error or is my entry incorrect?


Answer:
The deduction of the precamber in the serviceability limit state design is actually not regulated in steel structures. After numerous customer requests, we have adopted this in accordance with the TIMBER and CONCRETE add-on modules. However, according to the standard specification, this value should only be considered in the quasi-permanent design combination.
This does not apply to characteristic and frequent design situations. Thus, as soon as the design situation in the add-on module is adjusted accordingly (see image), the applied precamber is also subtracted from the resulting deformation.
