Q Figure below shows a three story frame with lumped masses subjected to latral forces,
together with its properties; in addition, the flexural rigidity is El for columns and beams.
a Identify the DOFs for representing the elastic properties and determine the stiffness
matrix. Neglect axial deformation of the members.
b Identify the DOFs for representing the interial properties and determine the mass matrix.
Assume the members to be massless and neglect their inertia.
c Formulate the equations governing the motion of the frame in the DOFs in part b
