Traffic in towns, quarry blasting near to towns often cause dynamic loads in buildings like residental houses which are designed for static loads only. . .In this paper it is shown by an analytical approach and numerical time history calculations for beams and beam systems that the vibration velocity is the best kinematic quantity for stress-evaluation.

The references listed in the following pages cover a good selection of research papers and applications in the area of vibrations of structural elements and systems.

Reliable methods for establishing limits on construction-related vibrations to minimize damage have been developed through the efforts of researchers.

The dynamic response of a large building floor system of a local college has been experimentally evaluated. The dynamic analysis of the floor indicates that the natural frequency and induced frequency are of the same order, thus the reason for the resonance problem. The dynamic analysis, experimental study, static analysis and recommendations for alleviating the resonance problem is discussed.

Large amounts of data have been collected on the response of high-rise buildings and test structures to ground motion generated by UNEs. These, couple with the response behavior of high-rise buildings to San Fernando's earthquake of 1971, provided unique opportunities to evaluate the behavior of reinforced concrete buildings responding to lateral motion. Some of the findings follow.
