Task 3 - Response of MDOF (weightage 30%) A three-story shear frame with masses lumped onto the floor slabs is shown in Figure 2. The beams are rigid in flexure and axial deformations in all columns are ignored. Column rigidity (EI). floor masses (m), force P and floor level at which P is applied shall be different for each student as per Table 3. 1. Formulate the equations of motions for the frame. 2. Determine the stiffness and mass matrices. 3. Determine the fundamental frequency and mode shapes 4. Plot the normalized mode shapes with corresponding frequencies. 5. Determine the frame response as a function of time if constant force P is suddenly applied at y floor level. z EL 68775 INm² In 2015 rum2
