The rules regarding the modeling of structural systems to be used in the linear calculation to be made within the scope of Design Based on Strength are as follows:

4.5.1. General Modeling Rules - Building structural systems will always be modeled in three dimensions . - The earthquake effect in two horizontal directions perpendicular to each other will always be taken into consideration. The vertical earthquake effect will also be taken into account according to 4.4.3 . - The extinction rate shall be 5%, unless otherwise specified. - The modeling rules given here are also applicable to non-earthquake loading cases.
