Response of Bridge Structural Members Under Wind-Induced Vibrations.

摘要

Structural dynamics of long slender member of contemporary cross-section shapes are investigated in a comprehensive manner for the purpose of precluding vortex excited vibration and mitigating damages to the member due to fatigue. The unique features are (1) the ends can have various degree of elastic restraint, (2) different levels of axial tension are allowed for both flexural and torsional vibrations, (3) flow regime can be either subcritical (single-frequency resonance) or supercritical (random shedding). The text consists of recommended design guide with design charts appended with supplements which show the basis of the design guide,mathematical theories,illustrative examples and a lengthy bibliography.
