Rotational capacity limited by bolt and weld failure (Stiffness analysis)

This article is also available in
ENCZDEESFRITPTNLHUROKRPLTHTRVIZH

In the older versions, the rotational capacity of the connection in the stiffness analysis was determined by 15% plastic strain of plates only.

Newly, the limit is defined by these three factors:

  • Failure of bolts (bolt steel failures in tension and shear)
  • Failure of welds
  • Plates (15% plastic strain)

This affects the Rotational capacity value Φc.
