First Steps with RFEM
Description
The current state of the development of finite element analysis software and computer technology allows for the calculation of more complex structure. More and more frequently, the FE calculation is performed on the entire model. In this context, certain practical construction problems may appear. One of these problems is the consideration of a construction process in the model.

In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member end releases. In addition to the nonlinearities ‘Fixed if’ and ‘Partial activity’, you can also select ‘Diagram’. If you select the ‘Diagram’ option, you have to specify the according settings for the activity of the member end release. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the release.

Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
