Symbols
R = Structural system behavior coefficient
D = Excess of strength coefficient
General Assessment
In accordance with the permitted building height class, BYS=6 ≥ 3, response modification coefficient for buildings where all the earthquake effects are covered by steel moment frames with high ductility level, R=8 and overstrength factor is given as D=3, according to TBDY Table 4.1.
Selected R and D Coefficients
C11 moment transferring frame is selected for both directions.
