I highly recommend Dlubal Software's Programs

Daily tasks in reinforced concrete design also include designing compression elements subjected to biaxial bending. The following article describes the different methods according to Chapter 5.8.9, EN 1992-1-1, which can be used to design compression elements with biaxial load eccentricities by means of the nominal curvature method according to 5.8.8.

With RF-FOUNDATION Pro, it is possible to determine the settlements of single foundations and resulting spring stiffnesses of the nodal supports. These spring stiffnesses can be exported into the RFEM model and used for further analyses.

If you select the combinatorics according to EN 1990 + EN 1991‑2 and define a load case in action category gr1a, gr2, or gr5, you have to additionally define in the program which load model should be taken as a basis for the load case. This information is crucial for defining combination rules for automatic combinations according EN 1990 + EN 1991-2. In the gr1a category, you can select TS (LM1), UDL (LM1), or pedestrian and cycle track, for example. TS (LM1) is preset by default. In the gr2 category, you can select breaking and acceleration forces or centrifugal forces as a specification.

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
