Determination of Modal Pseudo-Acceleration, Modal Displacement Increment and Cumulative Constant Scale CoefficientFactor

...

Any mode in C _Rn case of> 1 S as the earthquake data _from ⁽¹⁾ instead of C _R S _de ⁽¹⁾ received. This situation is shown in the above equation. Since the earthquake data is taken _from C _Rn S as ⁽¹⁾ , the and Their size should be calculated using ⁽¹⁾ _from C _Rn S. In this case, the displacement, plastic deformation or internal force values ​​calculated for the last step (X) and (Y) are calculated for earthquake loads as shown in the following equation.
