Contact stress between two plates
Non-linear contact between plates is essential for proper steel connection design.
Contacts are defined automatically in case of a bolt group definition or manually by a manufacturing operation. From now on, the contact stress between the two plates can be displayed. This helps to better understand the connection behavior and better model validity control (prying actions, deformation, etc.).
Contact stress results between the end plate and the column flange.
The values are shown in the check table of plates. However, the contact stresses are only informative and are not used in any check. Also, the through-thickness stress of shell elements is not considered.
This feature is available for the Expert and Enhanced version of IDEA StatiCa Steel.
