SUMMARY:

In structural projects, conventional analysis assumes a set of bars interconnected by nodal elements, and these connections are represented as completely rigid or flexible points.
The completely rigid connections indicate that the connectors transmit all the efforts between the elements and that there is rotational continuity. On the other hand, flexible bonds accept angular variation during the application of external forces.
Taking into account the concept of rotational stiffness, the EN 1993-1 standard classifies the connections as rigid or flexible, but there is an undefined intermediate region (semi-rigid connections). For the analysis of semi-rigid connections, several standards establish considerations to simplify the calculations and enable the design. In addition to the methodologies presented in standards, it is possible to verify the connections with the aid of the finite element method, which can lead to accurate results, but requires many computational resources.
The developed work seeks to evaluate the conservatism of the norms and propose a new equation for the calculation of semirrigid connections.
