Deflection Amplification Factor

The seismic amplification factor Cd can be input for each direction independently. It is recommended to use the default values fromult from ASCE 7 - Table 12.2-1 unless there are exceptional circumstances.

For bearing wall systems: Wood panels - 4 Other materials - 2.0

For building frame systems : Wood panels - 4.5 Other materials - 2.5

These are summarized for each material in Shearwalls in Seismic Provisions.

The seismic amplification factor is used in the calculation of story drift in 12.8.6, equation 12.8-15.
