Understanding the concepts on Degrees of Freedom

AIM:- Understanding the concepts on Degrees of Freedom

INTRODUCTION:-

• A degree of freedom is the number of possible movements of a structural system. The degrees of freedom can be used to describe displacements and rotations at a nodal point. Thus, each degree of freedom allows for a displacement or a rotation in a certain direction.
• In this project we have study the details conceptual degree of freedom in structural analysis

RESULT:-

• Calculated Ln , Mn and Γn for each of the five modes from the given equations.
• Calculated the effective modal mass Mn* and the modal mass participating ratio for the 5 modes.
• The base shear for each of the 5 modes of vibration are obtained.
• As per SRSS rule the combined base shear is obtained.
• The two modes are to be considered such that a modal mass participating ratio of obove 90% is obtained.
