1、附录 Study on the Propriety of Rayleighs Damping in Nonlinear Dynamic Analysis of Bridges Summary In this paper, based on the results of comparison of nonlinear dynamic analysis of 5 span bridges constructed on the I 、 、 regions by the two method (e.g. strain-energy proportional damping method & Rayle
2、ighs damping method), parametric study were made to the maximum bending curvature of the piers. As the results, it is found that the Rayleighs damping method brings a comparatively small approach to the bending curvature in many cases comparing with the strain-energy proportional damping method, and
3、 the bending curvature various in a comparatively larger areas. And also, comparatively computations were made to a complex bridge structures, e.g. 14 span bridge and a 3 span curved bridge. Suggestion was made on the practical use of the Rayleighs proportional damping method. Keyword: nonlinear, dy
4、namic analysis, the strain-energy proportional damping Rayleighs damping, bridges, the maximum bending curvature 1. Introduction After the new aseismic code of bridge design published in two years ago in Japan , the Rayleighs damping method are often used in non-linear dynamic analysis of bridges si
5、nce the assumption of damping matrix C=K+M, the time of calculating is shorter than other method . But through the computation to the many engineering problem, it shows that the results by Rayleighs damping method are various with the definition of the parameter. And also, it is found that the disco
