This paper studies the calculation of wind power bridge , seismic calculations, and wind in VIV Reynolds number effects , long bridges wind , seismic calculations has been studied separately , without the wind , seismic calculation method linked view of this, this paper elaborates wind , seismic calculation method based on the method of calculating the two made ??a detailed comparison , and the wind , seismic calculation method applied to engineering examples . Additionally, the paper in order to bridge engineering example Xiazhang produce an aspect ratio of 10:1 , the scale were the two main beams 1:25,1:50 section model , respectively, of the two main beams Festival segment model VIV tests and VIV occurs surface pressure measurement test model to study the Reynolds number effects on vortex characteristics of the vibration . The main contents are as follows : From the bridge wind , seismic calculation of the theoretical basis , static method , dynamic method to calculate three comparative studies and summarizes the wind , seismic calculations of similarities and differences . 2 to mule ditch bridge engineering background , the wind carried the bridge static calculation and analysis of the results of static calculations , the use of dynamic time-history method for seismic plastic analysis and the results analyzed, the bridge piers for shear checking . 3 by wind tunnel tests to study the effects of Reynolds number effects on vortex vibration amplitude ; study VIV vibration power spectrum Reynolds number effects ; study of vortex-induced resonance occurs, the Reynolds number under the effect of each measuring point by aerodynamic total aerodynamic correlation ; using vibration model to study the characteristics of the model surface pressure distribution , fluctuating pressure coefficient distribution , also studied the size of the average Reynolds pressure coefficient and fluctuating pressure coefficient distribution characteristics. Research shows that Reynolds number on vortex vibration amplitude , vibration power spectrum, reverse correlation coefficient , pressure, etc. have a great impact .
