摘要The response surface method was used to construct the explicit response equation between design parameters and structure response. This method was also used to analyze the sensitivity of the parameters. Accordingly, the influence degree of various design parameters on the response of long-span cable-stayed bridge was analyzed. The sensitivity factors of the design parameters solved through the explicit response equation could show the tendency of internal force, deformation, and cable force of a long-span cable-stayed bridge under the condition of changing design parameters. These design parameters were divided into four importance ratings according to the sensitivity percentage value. This task could quantitatively distinguish the influence degree of the design parameters on the structural response. The method could provide the reference for parameter sensitivity analysis and identification of a long-span cable-stayed bridge.
