A free vibration test is being conducted on a frame system as shown in Figure 2. With a jacking force of 90 kN applied, the frame is displaced 5 mm. Soon after jacking, the frame is released from the jack and its motion is recorded. On the first return swing after release, the frame does not come back to the release point but rather only 1 mm towards it. The time recorded between the time of release, and the first return is 1.5 seconds.
