It cannot be used with high ductility level.

The Complete Message:

Structural systems with high ductility level cannot be used in reinforced concrete systems with unidirectional gear floor.

In the article 4.3.4.3 of TBDY 2018 , it is stipulated that the carrier systems consisting of reinforced concrete frames with single-directional geared floors with or without filling will be classified as structural systems with limited ductility level and will only be used in buildings with DTS = 3 and DTS = 4.

For this reason, high ductility level is not preferred for unidirectional gear floor systems.

Possible solutions:

• A mixed selection of continuity level can be made by using the Analysis Settings / Earthquake Code wizard.

• The type of flooring can be changed. Girder / Cassette Floor type can be applied instead of unidirectional gear flooring.
