Add-on Module for RFEM 5
RF-PUNCH Pro

The RF‑PUNCH Pro add‑on module for RFEM 5 allows you to perform the punching shear design of singularly or linearly supported surfaces. The add-on automatically determines the governing punching load from the specified loading. It is also possible to manually apply the point punching load on a plate.

It allows you to automatically determine the punching load from the specified loading, and provides a variety of design options according to the standards EN and A1. The add-on module also supports user-defined National Annexes and provides numerous features for managing and displaying results.

Complete integration of results in the RFEM printout report

RF-CONCRETE Deflect | Input

The deformation analysis with RF-CONCRETE Deflect can be activated in the settings for the analytical serviceability limit state design in the RF-CONCRETE Surfaces module. Consideration of long-term effects (creep and shrinkage) and tension stiffening between cracks can also be managed in the dialog box above. The creep coefficient and shrinkage strain are calculated using the specified input parameters or defined individually.

You can specify the deformation limit value individually for each surface or for an entire surface group. The max. deformation is defined as the allowable limit value. In addition, you have to specify whether the undeformed or the deformed system is to be used for the design check.

RF-CONCRETE Deflect | Design

The deformation analysis according to the approximation method defined in standards (for example, deformation analysis according to EN 1992‑1‑1, 7.4.3) applies to the calculation of "effective stiffnesses" in the finite elements in accordance with the existing limit state of the concrete with or without cracks. These stiffnesses are used to determine the surface deformation by repeated FEM calculation.

The effective stiffness calculation of finite elements takes into account a reinforced concrete cross-section. Based on the internal forces determined for the serviceability limit state in RFEM, the program classifies the reinforced concrete cross-section as 'cracked' or 'uncracked'. If the tension stiffening at a section should be considered as well, a distribution coefficient (according to EN 1992-1-1, Eq. 7.19, for example) is used. The material behavior for the concrete is assumed to be linear-elastic in the compression and tension zone until the concrete tensile strength is reached. This is reached exactly in the serviceability limit state.

When determining the effective stiffnesses, creep and shrinkage are taken into account at the "cross-section level". The influence of shrinkage and creep in statically indeterminate systems is not taken into account in this approximation method (for example, tensile forces from shrinkage strain in systems restrained on all sides are not determined and must be considered separately). In summary, RF-CONCRETE Deflect calculates deformations in two steps:

Calculation of effective stiffnesses of the reinforced concrete cross-section assuming linear-elastic conditions
Calculation of the deformation using the effective stiffnesses with FEM

RF-CONCRETE Deflect | Results

After the calculation, the module shows clearly arranged tables listing the deformation analysis results. All intermediate values are displayed in a comprehensible manner. Graphical representation of design ratios and deformation in RFEM allows a quick overview of critical areas.

Since the design results are displayed by surface or by point including all intermediate results, you can retrace all details of the calculation. The complete integration of results in the RFEM printout report guarantees verifiable structural design.
