[poor English] About finite element approach

Traditionally RM Bridge has been developed as a program based on beam theory. A FEM implementation has been added later on. RM uses a hybrid approach, which allows for using beam and FEM elements in one and the same model. The advantage of this is, that also section-forces, which are required for ULS design code checks, are available, while primary results of standard FEM methods are stresses only.
