The cross-section describes the dimensions of a member in its section. Especially in steel construction it is describes as profile.
When creating a cross-section, all properties are defined which are necessary for the structural analysis (surface, moment of intertia, section modulus). A distinction is made between different cross-section types such as rectangular or composite cross-section.
One cross-section has to be assigned to each member in RFEM and RSTAB. Many cross-sections are saved in the library and can be selected there.
