Custom structural connections

Custom structural connections

This was a really unique problem. Our Customer reached out to us because they had to connect their structure, to the existing steel elements… but they could not use welding at all! And since the existing element was a huge vertical square pipe (and an I-section on a different location), both without any plates, openings etc. this was a really interesting challenge!

Of course, there were other limitations at play (about which bending moments can be transferred, etc. In the end, the design included two different custom connections that used pins, pre-stress tension rods (to provide friction) and a significant amount of elements.

Thanks to this solution, all of the Customers requirements were met, and the design was safely implemented.

Project Takeaway:

FEA is a really powerful tool! Without nonlinear algorithms, contact and pre-tensioning I don’t think we would be able to prove, that the proposed solution will work just fine. While designing each connection with FEA is definitely an overkill, there are some (like those) that simply require that treatment!

What Enterfea’s customers say

The first project we did with Enterfea was a silos design in 2015. Their non-linear FEA analyzes allowed to significantly reduce the costs of that project. Recently with the enormous support and commitment of Enterfea, we did a pressure vessel with imperfections design. Non-linear FEA analyzes allowed to save a project that seemed to be hopeless. The level of complexity and detail of analyzes provided by Enterfea always exceeds my expectations. Łukasz with his knowledge and commitment is a top-class expert in the field of FEA. Having 15 years of experience in the design industry, I can say that at the current level, Enterfea is no longer competing with the competition, they set new standards in the design projects and can only compete with themselves.

We have used Enterfea for a number of large steel tank designs. With the cost of raw materials increasing rapidly, it is vital for our customers that our designs are efficient whilst still being safe and code compliant. This is why Enterfera is so important. The level of detail involved in their complex non-linear analyses provide unrivaled value for money and the service is exceptional – Lukasz goes above and beyond to ensure any queries are answered even after a contract has been completed. His extensive knowledge of FEA gives us peace of mind that value is maximized and risk is mitigated as much as possible in our designs.

We have been working successfully with Enterfea for many years. Enterfea is always a reliable partner for the static design of our conveyor technology. In our current project, we are jointly developing a completely new, statically optimized conveyor system for integration into our standard.

Enterfea is performing all of the designs of silos for us with nonlinear FEA for over 5 years now, and we are very satisfied with the cooperation. Especially since our Customers appreciate the quality of the designs, which leads to more sales for us and no issues with verification of designs by the authorities.
