Rigid Connection, Shear As Joint Stiffness, Tensile Spring in Longitudinal direction
Channel: SHAHgordi
Date: 2023-07-09

This playlist series focuses on the rigid connection calculation according to EN 1993-1-8. A comparison is made with Ansys at the end of the series after hand calculation. Finally, tips for applying the semi-rigid connection to RFEM are presented.
A portal frame with two levels is presented. The Endplate welded to the HEA200 beam is bolted to a HEB300 column with 6M20 class 8.8. Steel material is S355 for all parties. 
In this video, the bolts are modified to join with Stiffness in shear and tensile springs are added for the bolt's longitudinal performance in Ansys. The contents are as follows: 
a) Shear Stiffness of bolts stated in the previous video
b) Longitudinal Stiffness of bolts model as tensile spring
c) Object Generator in Ansys of automation.
d) Activation of Beta in Ansys
e) Checking the results for:
   1)     Deformation,
   2)    Von-Mises Stress
   3)    Contact Tool
   4)    Moment Reaction
   5)    Beam rotational angle at support.
f) Comparison with the rigid joint and stiffness bolt models regarding Contact Tool and bolt forces. 

You can find the fast version of Bolt modeling in this playlist.
