• In the analysis made with semi-rigid diaphragm acceptance, the control of transferring the in-plane forces to the vertical elements is done automatically.

It should be shown by calculations that the in-plane effects are safe to transfer to vertical bearing elements in floors analyzed with the acceptance of semi-rigid diaphragm.
