1) (30 pts) A one story RC building has a roof mass of 700 kips/g, and its natural frequency is 6 Hz. This building is excited by a vibration generator with two weights, each 75 lb., rotating about a vertical axis at an eccentricity of 15 in. When the vibration generator runs at the natural frequency of the building, the amplitude of the roof acceleration is measured to be 0.05 g. Determine the damping of the structure. (g=386.1 in/s?)
