About IDEA StatiCa

We develop software for structural engineers and detailers. Our development team researches, tests, and applies new methods of analyzing the behaviour of structures and their members. Based on this, we created IDEA StatiCa – software that enables engineers to work faster, evaluate requirements of the national code thoroughly, and use the optimal amount of material. For us, creating software is a way to contribute to making every new construction around the world safer and cheaper.

Rotational stiffness of EEPC connection

How does a beam web opening influence the rotational stiffness of the EEPC connection and the code checks?


Before IDEA StatiCa, that was a really tough question to answer for anyone, and only with the use of sophisticated non-linear analysis software – and lots of hours – someone could reach a safe conclusion about rotational stiffness.

In a quick test we did on a Beam-to-beam eccentric end plate connection, we saw a 10% decrease in rotational stiffness by introducing a web opening. Depending on the loading, this could lead to a significant change in its behavior, and therefore further investigation in the overall design could be required.

With IDEA StatiCa, such questions can be answered within minutes, in a safe and code-compliant way!
