The 2021.e version of StruBIM Shear Walls also includes program corrections that solve errors that could arise in specific circumstances:
The following Eurocode checks have been implemented in the 2021.e version of StruBIM Shear Walls:
As of the 2021.e version, StruBIM Shear Walls can be installed in Catalan, English, French, Italian, Portuguese and Spanish. In previous versions, the program could only be installed in English and Spanish.

The analysis process has been optimised to obtain intermediate results and so speed up the on-screen view when the section of the wall is changed. This optimisation is most noticeable when the number of combinations is higher.
New panel in which forces are represented graphically. When the "Forces" button is pressed, users access a panel that displays the combination force envelopes of the selected wall.
The Mexican NTC-RSEE 2017 has been implemented in the 2021.a version of StruBIM Shear Walls.
Some standards, such as the NTC-RSEE 2017 (Mexico) or Eurocode 8, consider the amplification of forces in shear walls in their articles. This new feature allows users to consider amplified forces for normal and shear force checks.
The amplification of the forces is defined independently for bending moments, axial forces and shear forces.
Default values are assigned based on the standard that has been selected in the BIM model import process. However, a value assignment button has been implemented according to the configuration of the standard (blue arrow).
The program generates a new group of combinations and a new check for amplified forces depending on each case, but still performs a check with the original forces (not amplified).
The bending moment amplification is based on the definition of a height that raises the force law from the original moment at the base of the wall.
The amplification of the axial forces is defined using a factor that has the effect of enlarging and reducing the axial force, since initially, it is unknown which will have the most unfavourable effect. This duplicates the amplified combinations with respect to the original ones if it is applied.
The shear force amplification is applied using three parameters, one that directly amplifies the shear at the base of the wall, another that defines the height as of which the amplified shear law changes direction to the shear at the highest point, which is defined by a third parameter and will be a function of the amplified shear at the base.
The amplification of axial forces and/or moments will generate new amplified force combination groups for normal and shear force checks. Users must bear in mind that the checks of normal forces is carried out using the global forces of the wall, and the shear check is carried out on the forces that have been transformed to the segment, taking a segment as being each span that makes up the complete wall on plan.
“StruBIM Design Coupling Beams” is a new module of “StruBIM Shear Walls” brought about to design and check coupling beams that are reinforced with diagonals. It is integrated into the Open BIM workflow.
“StruBIM Shear Walls” imports the coupling beams from the Open BIM project to which it is connected, together with the analysis results. Using this data, “StruBIM Design Coupling Beams” allows users to design, edit and check the reinforcement of the beams. Once the reinforcement design process has finished, the results can be generated and exported. The program provides reinforcement description reports, check reports (summarised or extended) as well as a 3D view of the results.
More information will be available shortly.
In the 2020.e version, the design process has been improved to obtain more optimised reinforcement.
As of the 2020.e version, "StruBIM Shear Walls" can interpret ETABS® structural models from the "ETABS 2016" and "ETABS 18" versions (ETABS® is a registered trademark of Computer & Structures, Inc). "StruBIM Shear Walls" obtains the information that is required to design the shear walls from this structural model.
"StruBIM Shear Walls" users can import the structural model from ETABS® using two methods:
