The Steel Design module in FEM-Design takes new leaps with the function Plastic Hinges

The Steel Design module in FEM-Design takes new leaps with the function Plastic Hinges The release of FEM-Design 21 is just around the corner and a big new feature when it comes to the steel module is Plastic Hinges. With this tool, a plastic distribution of the stress across the cross section can be obtained and plastic mechanisms in the structure appear. This will also potentially affect the load distribution and provide a more realistic behavior. This type of calculation uses a more advanced stiffness matrix for the Timoshenko beam theory, which includes a coupling part between the curvature and the axial strain. Due to this, a more nuanced behavior can be obtained, for single symmetrical profiles for example. If plasticity occurs in the cross section, the neutral axis can potentially move and consequently an axial load can cause curvature of the beam. How does this function work practically in the program? Start by choosing whether or not you want to take plasticity into account. This is done under the "General" tab at object level. Here the user can choose whether they want to take plasticity into account in any specific load combination. Then the analysis is run with the "PL" setting selected under the settings for the load combinations (Setup by load combinations). An iterative process is now performed in which a plastic distribution of the stress across the cross section is allowed. If the force cannot be redistributed to other parts of the structure, the calculation will stop and present the result of the last converged load step. FEM-Design also shows the first unstable position. With the help of these results, the designer gets a very good understanding of the mechanism and how it can potentially be avoided. Under "Detailed results" for the stresses in the beam, we can see how the plastic distribution looks across the cross section. The program uses an idealized elasto-plastic material model where the limit for plasticity is set to fy (e.g. fy = 355 for S355). Due to this, a smaller elastic part is obtained in the profile as the curvature is not infinite. This can also be seen in the picture above in the middle of the profile where the tension in the cross section is less than 355 MPa. FEM-Design 21 is expected to be released at the end of January 2022 and it is the version with the most new features that we have released so far! Do not miss all the news that will be rolled out in the near future and feel free to take the opportunity to book a demo of the new version in your office. Just get in touch with one of our customer coaches and we will be happy to help you with this! Sincerely StruSoft team

Using masonry walls as stabilization?

Using masonry walls as stabilization? In Sweden, the masonry wall is mostly used as a shell wall, i.e. as climate protection. In our neighboring countries, on the other hand, its load bearing capabilities are often considered as well. However, occasionally we get support questions about whether our programs can handle load-bearing masonry walls, which is our cue to introduce Masonry Design. With this program, in addition to designing the masonry wall/column for vertical and horizontal loads with or without reinforcement, you can also calculate shear walls that are included in the building's stabilizing system. As an example, we study a T-shaped wall made of solid brick with the above dimensions. The following vertical and horizontal loads are applied on the wall. A calculation shows that the wall becomes unstable due to the large horizontal force. An opportunity to get the wall stable is of course to increase its size, and thus self-weight, but this is usually not a feasible option. Another way is to reinforce the wall vertically. Let’s give it a try. We choose 6 reinforcement bars with a diameter of 10 mm placed in hollow stones 4 meters from the left edge of the wall. The bars must of course be anchored down to the underlying slab. We now get a stable wall but the shear capacity in the wall is insufficient. To handle this, we also choose to reinforce the wall horizontally. The program chooses to reinforce every sixth joint with double bars of 6 mm in diameter. The shear capacity in the wall is now sufficient. Another problem remains, namely the shear capacity between the wall and the concrete slab underneath. To solve this, shear dowels can be used. We choose dowels with 12 mm diameter. The program's calculation shows that 6 dowels are required between wall and plate to obtain sufficient capacity. The wall can now handle the applied loads.

New Partnership between SPACE GASS and StruSoft

December 23, 2021 – StruSoft AB is pleased to announce a new partnership with ITS Pty Ltd, the developer and supplier of SPACE GASS, the Australian market-leading and user-friendly structural analysis software. Space Gass Pty Ltd, the Australian subsidiary of StruSoft AB, has taken over ownership of all assets related to the SPACE GASS software. All former employees of ITS Pty Ltd have transferred their employment to Space Gass Pty Ltd, including CEO Peter Schulze. SPACE GASS is a multi-purpose 3D analysis and design program for structural engineers.  Its extensive range of features makes it suitable for anything from beams, trusses and frames to buildings, towers, tanks, cable structures and bridges.  Capabilities include a 64-bit multi-core solver, silky smooth 3D rendered graphics, plate finite elements, frame elements, cable elements, tension/compression-only elements, moving loads and links to many CAD and building management programs. StruSoft is majority-owned by Vind, a Norwegian based industrial owner company with an eternal perspective for all its businesses. The new ownership will make sure SPACE GASS users experience continuity as their favourite structural analysis software is further improved, maintained, supported and kept up to date by the same local Australian organization. “I firmly believe the new partnership with StruSoft will have a very positive impact for all SPACE GASS customers and users. StruSoft will accelerate investment in new and improved SPACE GASS functionality, hire more talented engineers locally and safeguard the local Australian support function. All of us at Space Gass Pty Ltd are very much looking forward to this next part of our journey and continuing to support our customers” - Peter Schulze (CEO Space Gass Pty Ltd) “Space Gass will become a very important member of the Strusoft family. I have great respect for Peter, his team and what they have achieved so far. I am especially impressed by the broad range of technical capabilities inherent in the software in addition to the strong Australian team supporting a large and growing community of customers in Australia and abroad” - Jan-Willem Koutstaal (StruSoft’s Chairman of the Board) Please contact us at info@strusoft.com if you have any questions related to the above information.
