In the structural analysis programs RFEM and RSTAB, it is possible to consider member nonlinearities (for example, failure at compression/tension, slippage, tearing, creeping) as well as support and release nonlinearities such as failure, creeping, friction support, and so on.
In addition to linear static analysis and second-order analysis, large deformation analysis is also available (for cable design, for example). Moreover, RFEM supports the consideration of material nonlinearities such as plastification, concrete in cracked state (state II), and many others.
