英文摘要	Vibration has become a serious serviceability problem due to the large openings of girder, lightweight floor systems, and high-strength materials used in practice. The results from both heel-drop and jumping floor vibration tests of a large-span prestressed cable RC truss (PCT) floor system are presented. System parameters such as peak acceleration, fundamental frequency, and damping ratios were considered and studied. The results and comparisons were taken based on the on-site test data. The comparison results indicate inconsistencies with the heel-drop or jumping impact models proposed by other researchers. The results from heel-drop and jumping tests were comprehensively compared against published codes. Based on the classic plate theory, a derived accurate formula for a PCT floor system is proposed. Lastly, a simplified method is suggested, which uses the constant moment of inertia for the cross section of a PCT girder. (C) 2015 American Society of Civil Engineers.
