DPWH-BODb) Elastic Seismic Response Coefficient for Multimodal Analysis, Csm

Csm = 1.2AS / Tm2/3

where: A = acceleration coefficient S = site coefficient Tm = the period of the mth mode of vibration Limitations: Csm < 2.5A Csm < 2.0A for Type III & IV soils where A > 0.30

Exceptions: For Type III & IV soils with T < 0.30 sec, Csm = A(0.8 + 4.0Tm)

For structures which Tm > 4.0 sec, Csm = 3AS / Tm4/3BRIDGES DIVISION
