Understanding the concepts on Degrees of Freedom

Aim:To calculate L_n , M_n and Γ_n for each of the five modes and to obtain the base shear for each of the 5 modes of vibration and the combined base shear as per SRSS rule.

Procedure:

_Result:

• _{Ln,Mn,Tn values are calculated for each of the 5 modes}
• _{The base shear force for each of the 5 modes are obtained}
• _{Effective modal mass and the modal mass participating ratio for 5 modes are obtained.}
