| Abstract: | Combining Matlab with the MIDAS CIVIL calculation software, the application of improved response surface method is shown by calculating and analyzing the reliability of the rotation angle at beam ends of Xinkai River Bridge of Harbin-Dalian high-speed railway which is the first long-span steel-box stacked arch bridge for high-speed railway in China. The calculation results show that the re liability of the rotation angle at beam ends of Xinkai River Bridge can meet the requirements according to the improved response surface method. |
