Frequently asked questions: Tekla Structures Subscription licensing

General

What is the difference between a subscription license and a perpetual license? With a subscription license, you typically pay for an annual subscription. While the subscription is active, you have access to support, upgrades, and online services. With a perpetual software license, you pay for the software when you…

Import a model from a Semantic TrimBIM file

Submitted by tekla.document… on

Import a model from a Semantic TrimBIM file Semantic TrimBIM import is a two step process as follows: Use the Reference Models pane to import the reference model from a TrimBIM (.trb) file. For instructions how to do the above, see: Import 3D reference models. Once the reference model has imported, right-click the reference model name in the Reference Models pane and select Import Semantic Model from the context menu. Then, (as illustrated below): Make appropriate selections from each page…

Import Semantic Model dialog

Submitted by tekla.document… on

Import Semantic Model dialog The Import Semantic Model dialog, which is accessible from the Reference Models pane, is used to import models from Tekla Structures to Tekla Structural Designer. To open the Import Semantic Model dialog: Open the Reference Models pane. Right-click on the reference model name in the dialog that you want to import. Select Import Semantic Model from the context menu. The dialog has four pages as described below:

Semantic TrimBIM Import (Steel)

Submitted by tekla.document… on

Semantic TrimBIM Import (Steel) New in release 2025 - A new ‘Import Semantic Model’ approach for Engineers who use Tekla Structures for analysis and design during early stage design. The new workflow is initially for steel members only. Covers ‘main’ structural members Beams, Columns and Braces. Other ancillary steel members also integrated. Transfer is based on the geometric location inside Tekla Structures. The analytical model is automatically generated in Tekla Structural Designer to…

Submitted by tekla.document… on

Release notes: Tekla Structural Designer 2024 SP4 This release will update your Tekla Structural Designer installation to version number 24.4.0.70 and should be installed to ensure optimum function of the program. It includes a number of new features, enhancements and issue resolutions as detailed below. If you are upgrading from a version earlier than the immediately prior release of 2024 SP3 (version 24.3.1.0 released November 2024), you can find details of requirements, enhancements and fixes for all previous releases in Tekla User…

Masonry wall limitations and assumptions

Submitted by tekla.document… on

Masonry wall limitations and assumptions The following limitations and assumptions apply to the design of masonry shear walls in Tekla Structural Designer:

Limitations

General Seismic design is not currently considered in masonry wall design. Loads are distributed based on finite element stiffness. As such, specific limitations per TMS 402-22 5.1.1 and 5.2 are not considered. Masonry walls are modeled as homogeneous elements with solid cross sections. As such, shell analysis results may not correspond…

Semi-rigid mesh definition

Submitted by tekla.document… on

Semi-rigid mesh definition You can use a mesh of semi rigid 2D solver elements for slabs and decks by setting their Diaphragm option to "Semi-rigid". The semi rigid mesh density is set globally, but you can override it at individual levels if required. Adjust global semi-rigid mesh properties Initially, the same mesh properties are applied globally to all semi-rigid slabs. In order to adjust the global mesh properties, see the following instructions. Go to the Project Workspace. In the Structure tree, click Structure.…

Work with meshed walls and slabs

Submitted by tekla.document… on

Work with meshed walls and slabs In terms of finite element meshing in Tekla Structural Designer the following mesh variations exist: Wall mesh Slab mesh Semi-rigid mesh Meshes are always planar. Within each slab plane there can be many mesh groups. (A mesh group being an area of interconnected slab items which have the same properties, hence allowing the area to be meshed as one.) FE mesh creation is carried out independently for each mesh group in turn. FE meshes interconnect along the lines where mesh groups meet (this…
