Structural system type A14 (in X / Y direction) is selected. Shearwalls should be used in A14 structural systems. |
...
The A14 structural system is defined in the earthquake code as buildings where all the effects of earthquakes are met with high ductility level non- void reinforced concrete walls.
However, the shearwall is not defined in the project.
Possible solutions:
Shearwalls should be added in the requested direction in accordance with the A13 structural system in the project .
If a shearwall will not be used in the structure, in the Analysis Settings / TBDY 2018 Earthquake Code Wizard, A11 for High Ductility Level Systems and A31 for Systems with Limited Ductility Level can be selected.
