• Nonlinear calculation method selection is under user control.

Any of the nonlinear methods can be chosen to determine the earthquake performance of existing buildings with the Assessment and Design Based on Shaping (ŞGDT) approach. These methods 5.6 'as described in Single Mode Push Methods , 5.6.6 ' as described in Multi-mode push Methods with 5.7 'as described in the Time Domain of Nonlinear Analysis Methods ' dir.

Nonlinear calculation methods to be used for determination of structural performances of existing or strengthened buildings under the effect of earthquakes and strengthening calculations are applied with the methods explained in Section 5 of TBDY . However, TBDY Chapter 5 is used in determining the performance of new buildings. Therefore, the following conditions are applied when determining the earthquake performance of existing buildings.
