1.1 Add-on Module RF-MOVE Surfaces

The RFEM add-on module RF-MOVE Surfaces makes it possible to easily create load cases for loads moving over surfaces. These loads can be relevant in different fields, for example, vehicle loads on bridge constructions. Based on the moving load's load positions, RFEM generates separate load cases for RFEM. Optionally, an enveloping result combination of all load positions is created.

In order to generate the load cases, you only need to define the load parameters (such as type of load, distance between load positions) and the moving distance. A library with load models for vehicle loads helps you to define the loading. Individual load schemes can be stored in a user library. The add-on module also allows for considering influence lines and surfaces from RF-INFLUENCE.

RF-MOVE Surfaces includes useful control parameters for generating load cases. The lanes' single or area loads can be arranged parallel, eccentrically, or with off-set. Moreover, they can be limited by bumpers. An extensive database offers access to various load models according to EN 1991-2 [1].

Normally, the load cases of moving loads are created as new cases for RFEM. Alternatively, they can also be added to existing moving load cases.

We hope you will enjoy working with RF-MOVE Surfaces.
