Q6 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)
Q 6 Figure below shows a three - story frame with
