62 Advanced Training To enter this correctly, it should be performed using a non-linear spring or a non-linear function in Scia Engineer: If everything is being filled out in the values for this hinge, the following dialog appears:
63 Scaffolding It is assumed that the translations are “rigid” in all directions. Also the rotation around the x-axis is considered as “fixed”. This is only a rough estimate. For the rotation around the y-axis, the non-linear function (determined earlier) is entered with a linear rigidity of 0,051 MNm/rad. The rotation around the local z-axis will be much smaller than around the y-axis namely 0,0051 MNm/rad. For the values of Vyk, the same value is taken as for Vyz. This value should be determined by the supplier as well. For the maximal moments the same conclusion can be drawn. Subsequently these hinges are attributed to both extremities of the ledgers and guardrails. Connection between wind bracings and Standard For the connection between the wind bracings and the columns, the rotation around the local y-axis is free. There can be a discussion about the rigidity around the z-axis. In this example, it is set on “rigid”, although it cannot be completely considered as “rigid”. If you want to enter the exact value, you have to ask the supplier. The rotation around the x-axis and the translations in the x, y and z direction are “rigid”. In the direction of the member (local x direction) there is a certain margin of these wind bracings. This can be entered by adopting “Spacings”. For this purpose, all bracings are entered as a “non-linearity” on the members, containing the type “Spacing”. Subsequently a margin of 1 mm per member is entered:
