This volume deals with dynamic deflections of concrete structures. The collection of 12 papers leads off with a review of the state of the art. Other subjects include: vibration criteria for long-span concrete floors, dynamic characteristics of reinforced concrete buildings, estimation of dynamic stressing of floors and buildings due to shocks and blasting, frequency matching in continuous post-tensioned bridges, dynamic sway characteristics of structures, dynamic response of noncomposite metal deck floor system, concrete structures and construction vibrations, prediction of damage to low-rise buildings due to vibrations created by blasting, vibration performance of industrial buildings. A bibliography is included.
