According to code EN12811-1, the connection column - column can be considered rigid
in the modelling
A hinge will not be entered at the extremities on the standard
Standard – Ledger and Standard – Guardrail connections
- y direction: 0,10 MNm/rad
- z direction: 0,005 MNm/rad
These rigidities are obtained from data from the supplier. In this case, the rigidity for the y direction is
taken from the supplier and a smaller value is taken for the z direction. Of course, this is not a
correct method. Both should be obtained from data from the supplier.
Standard – Toeboard and Ledger – Floor board connections
- y direction: Hinged
- z direction: Rigid
Standard – Bracing connections
Summary:
SUPPORTS
- y direction: Hinged
- z direction: Rigid
As a summary, the following rigidities can be entered in Scia Engineer:
Standard-ledger: y direction: 0.10 MNm/rad
z direction: 0.005 MNm/rad
Standard-guardrail: y direction: 0.10 MNm/rad
z direction: 0.005 MNm/rad
Standard-bracing: y direction: Free
z direction: Rigid
Standard-toeboard: y direction: Free
z direction: Rigid
Ledger-floor board: y direction: Free
z direction: Rigid
There are two types of supports: the base jacks at the bottom and the anchorages in the wall.
For the base jacks, translations in all directions are fixed (Translations X, Y and Z fixed). For the
anchorages, only the translations according to the x and y direction are fixed (Translations X and Y
fixed).
The anchorages are introduced according to the anchorage scheme: from 4m high, every standard
has to be anchored every 4 m upward. Over 20 m high, this needs to be performed every 2 m upward.
