For automatic load case combination in RFEM and RSTAB, you have to enter the possible interaction of load cases. In addition to the simultaneous or alternative occurrence of all load cases of an action, an option for different combination conditions is possible.
In addition to the basic combination rules of EN 1990, there are other combination conditions for actions on road bridges specified in EN 1991‑2 that must be taken into account. RFEM and RSTAB provide automatic combinatorics that can be activated in the General Data when selecting the standard EN 1990 + EN 1991‑2. The partial safety factors and combination coefficients depending on the action category are preset when selecting the respective National Annex.
The fundamental requirements of a structural system are (according to the basis of structural design) sufficient ultimate limit state, serviceability, and resistance. Structures must be designed in such a way that no damage occurs due to events such as the impact of a vehicle.
In addition to determining loads, some particularities concerning the load combinatorics in timber design have to be considered. Contrary to steel structures, where the largest loading results from all unfavorable actions, in timber construction, the strength values depend on the load duration and timber humidity. Special characteristics have to be considered as well for the serviceability limit state design. The following article discusses the effects on the design of wooden elements and how this is possible with RSTAB and RFEM.
Utilize all the options of the 'Edit Load Cases and Combinations' dialog box to facilitate your work. Here you can automatically create load and result combinations after selecting the corresponding combination expressions. In this clearly arranged dialog box, you can also e.g. to copy, add, or renumber load cases.
Additionally, control the load cases and combinations in Tables 2.1 – 2.6.
The Base Data dialog box includes a wide range of standards and the option to create combinations automatically. The following standards are available:

For design objects, you can optionally display sags or extreme results.
The results of solid stresses can be displayed as colored 3D points in the finite elements.
I have used the RF‑/DYNAM Pro add-on module to generate the governing result combinations of seismic loads. What is the subsequent procedure to carry out the design of the individual structural components?
I design timber components. The deformations of the load combinations deviate from the manual calculation by exactly the coefficient of the material partial safety factor. What can be the cause?
How can I consider loads from the self-weight as "favorable" and "unfavorable" for the combinations?
For a specific combination expression, I would like to consider a load case with a combination coefficient that deviates from the standard. How can I proceed?
I have created automatic load combinations according to EN 1990 + 1995 (CEN). Although Ψ2,1 = 0, factors greater than zero are applied for wind and snow. Is it a program error?
I am using automatic combinations, but some load cases are not used in the generated combinations. How can I change this?
