fis-1269	Guodong, Wang	The research for mechanics stimulation method of nonlinear random vibration based on statistical linear theory	2014	9	.pdf	application/pdf	4780	176	44	The Comparison between Absolute Displacement Method and Random Vibration Method The charts in Fig. 3 are to respectively represent that the main span of cable-stayed bridge, the power spectral density of back span are influenced by several factors in the case, where the linear points denote random vibration method, the dashed points denote absolute displacement method. We analyze from the area surrounded by curve and the abscissa that the mean square value of seismic random vibration wave obtained through calculation with absolute displacement method is on the smaller side, namely the energy acting on cable- stayed bridge is too small, and it demonstrates that random vibration method is a kind of seismic analysis method, which is conservative in relative speaking.	cache/fis-1269.pdf	txt/fis-1269.txt
