Question 3: Consider a two-storey shear building frame as shown below. The mass of the frame is assumed to be lumped at the floor levels and the floors are considered rigid. The floor masses are indicated in the figure. The total lateral stiffness of the first storey is 3ko and the total lateral stiffness of the second storey is 2ko. Determine the natural frequencies (Hz) and mode shapes of the frame. mo 2 2ko 2mo 1 3ko
