In the course of the Elbe-Havel Canal expansion, the Güsen road bridge was replaced by a new construction at the same location. This new construction was necessary because the clear width and height of the existing bridge were not sufficient for the next development of the waterway.
In order to maintain an important road connection over the canal, the construction of a temporary bridge was required.
The company grbv Ingenieure im Bauwesen GmbH & Co. KG from Hanover, Germany, was responsible for the planning and structural design of the new and the temporary bridge as well as for the demolition of the existing bridge. For the static calculations, grbv used a.o. the framework program RSTAB.

Plate girder is an economical choice for long spans construction. I-section steel plate girder typically has a deep web to maximize its shear capacity and flange separation, yet thin web to minimize the self-weight. Due to its large height-to-thickness (h/tw) ratio, transverse stiffeners may be required to stiffen the slender web.

The calculation of complex structures by means of finite element analysis software is generally performed on the entire model. However, the construction of such structures is a process carried out in multiple stages where the final state of the building is achieved by combining the separate structural parts. To avoid errors in the calculation of overall models, the influence of the construction process must be considered. In RFEM 6, this is possible using the Construction Stages Analysis (CSA) add-on.
The determined values for the influence ordinates are displayed as decimal numbers with up to six decimal places by default. This is usually sufficient for the influence lines of internal forces.
The RF-MOVE/RSMOVE add-on module does not display any result windows: You can check the created load cases, including loads, in RFEM/RSTAB. Descriptions of the individual moving loads are created on the basis of the respective load increment number.
However, it is possible to modify the descriptions in RFEM/RSTAB. You can export all data in tables to MS Excel.
You can create various load cases with a single mouse click. After the generation, the numbers of created load cases and result combinations are displayed.
Sets of members with moving loads are selected graphically in the RFEM/RSTAB model. You can apply several different types of loads to one set of members at the same time.
By specifying the first load position, you can precisely display the load entering the runway of the continuous member. In the same way, it is possible to define whether a moving load consisting of various load applications is allowed to move beyond the end of continuous members (bridge) or not (crane runway).
The increment of the individual load positions is determined by the number of load cases generated for RFEM/RSTAB. You can also add loads to already existing RFEM/RSTAB load cases so that no additional superposition is required. Several load types are available, for example single, linear and trapezoidal loads as well as load pairs and several uniform concentrated loads.
It is possible to apply the loads in local and global directions. The application can refer to the true member length or to the projection in a global direction.
- Generation of up to 9,999 load cases from moving load positions
- Parameterized load positions of various concentrated and distributed loads
- Summary of several moving loads in one generation case
- Possibility to add loads to the already existing RFEM/RSTAB load cases
- Generation of a result combination to determine the most unfavorable load position
- Possibility to save load specifications for further use in other structures
