Within MINEA, it is now possible to take reinforced concrete columns into account in the wall design according to their design in the construction process. If, for example, the reinforced concrete columns are constructed in formwork blocks in each storey and decoupled from the vertical load transfer by appropriate measures (e.g. decoupling with polystyrene), it is now possible to take this into account when determining the internal forces and during the wall design. Decoupling the reinforced concrete columns from the vertical load transfer means, for example, that the static load cases and the resulting internal forces are determined on the system without reinforced concrete columns and the determination of the internal forces due to dynamic load cases (response spectrum method) is carried out on the overall system consisting of wall panels and reinforced concrete columns. When verifying the walls, the internal forces from the different load cases or systems are then combined. If necessary, the reinforced framing within the formwork blocks can also be taken into account in the shear force verification by using the entire wall length as the compressed length.

The functionality on which the report generation is based has been revised and accelerated. Especially for large sample buildings with a large number of structural elements (walls, columns, ...) and load cases, this revision is noticeable in a significant increase in speed.

The new 3D calculation module is based on a brand new powerful 64-bit based kernel, which enables significantly faster calculation and modeling of larger 3D models. As part of the introduction of the new kernel, the limit of 100 walls/columns has been removed for three-dimensional modeling. In addition, the coupling mechanisms have been completely revised. These can now be defined separately for masonry and reinforced concrete walls to allow for different types of connections. In addition, a new column type has been introduced for modeling rigidly connected columns.

The previous graphical representation of the wall internal forces was extended by the possibility to display the column internal forces. For the wall integration objects, the possibility of visualizing the different distributions on the 3D model was also created.

The subsoil classes of the German earthquake zones have been published digitally in DIN EN 1998-1/NA/A1:2023-02. These are now automatically determined for the current location based on the data from DIN EN 1998-1/NA/A1 when selecting the spectral acceleration via the site search in MINEA Linear.

The newly implemented data interface BIM-SAF (Structural Analysis Format) is a data format based on MS-Excel© for the smooth exchange of calculation models. With the BIM-SAF data interface, models can be efficiently imported from common BIM and calculation software for the structural verification in MINEA. MINEA is an ideal supplement to your design software and the input effort is reduced to a minimum.

The earthquake hazard maps according to DIN EN 1998-1/NA-2021 have been integrated and the earthquake data for the building location can be determined interactively by entering the address data with OpenStreetMap©.

• The input of wind loads according to DIN EN 1991-1-4/NA-2010 is now supported by an interactive wind load database. The wind loads on common building shapes can be determined automatically.
• Consideration of inclinations and verification of effects according to second order structural theory

The extensive mathematical verification options for the current wind and earthquake effects are now available in the following verification modules.

• Computational verification with two-dimensional calculation models with automatic consideration of framing effects according to DIN EN 1996-1-1/NA-2019, Annex K

• Computational verification with three-dimensional calculation models.

Simplified verification according to the design rules based on the new regulations for required shear wall areas.

The slab design for the additional loads due to framing effects in 2D calculation models has been supplemented. For the additional bending and shear loads, the required reinforcement required is now checked with output in the automatically generated verifiable structural analysis.

With the new approval databases for DIN EN 1996, the latest products of the masonry industry are available. Please use the download offers of the approval databases on the MINEA homepage.

In the linear earthquake verification, the higher behaviour factors q according to DIN EN 1998-1/NA-2021 can now be applied. This results in significantly improved verification possibilities.
