Connection Wednesdays – September 20th

Are you a trial user? Have you recently purchased a license? Or are you already an advanced IDEA designer and you want to learn more about IDEA StatiCa?

Then join our Wednesdays’ regular webinars, and find out more about this breakthrough technology that has changed forever the way we analyze & design steel connections!

Every day, more and more structural engineers are discovering IDEA StatiCa and implement it in their design workflows. Consulting firms of every size, steel fabricators, and other professionals that deal with steel structures, are taking advantage of this exciting new technology that allows them to design joints of any topology and loading easily and safely, saving a significant amount of time, and achieving more economical designs.

We are organizing this series of free regular webinars on Wednesdays to inform anyone that wants to know in detail how IDEA StatiCa works, and how it can be integrated into the BIM workflows.

During the webinar, you will see the whole workflow of modeling, loading, and check of one “Interesting joint” a real life design example, and one “HelpDesk highlight” a real user problem with a solution to it. At the end of each webinar, there will be a Q&A section, where we will answer any questions from the audience.

So don’t hesitate, simply register for one or more days, and learn how IDEA StatiCa can help your business.

On Wednesdays, we run two same sessions: the first at 11:00 CEST (Amsterdam time), followed by another one at 12:00 EDT (New York time). Register below for both at the same time and join the session that fits your day.

Join the Webinar and learn about:

  • How to quickly use IDEA StatiCa to design and check steel connections
  • How to model your joint efficiently
  • Avoiding modeling mistakes from user examples
  • Exporting connections from CAE/CAD programs to IDEA StatiCa
  • How to minimize the risks of structural defects even in complex nodes or connections
  • How to deliver clear results for verification

Truss Design:

The booms of the truss was rotated through 90°, for increased buckling resistance out of plane. The purlins provided restraint to the top boom whilst diagonal knee braces were used to create bottom boom restraints off the purlin. The knee braces also propped the purlin putting tension into the 90x90x10 RSA vertical truss internal.

Top Boom Connection Solution:

The simplest connection solution was to provide a toe plate across the flanges of the boom, onto which the CHS truss internals could be welded. In effect this replicated an SHS hollow section but allowed for plate thickness to be increased locally at little cost.

An additional gusset plate was used to pick up the vertical RSA and also provide stiffness to the joint.

The end reactions from the purlins were negligible, therefore a fin plate would suffice to deal with the axial loads generated. An additional fixing plate was provided over the top of the boom to continue the fixing face of the purlins over the connection.

The connection was designed in EPS mode to check stresses across joint for the specific load combination. To ensure equilibrium was maintained, moments generated by member offsets were applied to the ends of each member. Welds were checked using the average stress rather than maximum stress.
