A31 carrier structural system can only be used in buildings with Earthquake design class (DTS) 3 or 4. |
A31 type carrier structural system TBDY 2018 is defined in Table 4.1 as buildings where all earthquake effects are met with moment-transferring reinforced concrete frames with limited ductility level .
TBDY 2018 4.3.4.3 by the substance transfer torque entire seismic effects ductility limited carrier structural system are met with reinforced concrete frame ( Table 4.1 from A31 , B31 , C31 conveyor systems) will be used only in buildings with DTS = 3 and DTS = 4.
...
If BYS> = 3, buildings without curtain shearwall can be selected as A11.
If BYS> = 2, the building can be selected as A14 or A15 , taking into account the conditions given in Article 4.3.4.5 .
...
Considering the conditions given in 4.3.4.5, one of the carrier structural systems A21 or A22 can be selected.
