摘要
基于改善响应面法,结合Matlab与MIDAS CIVIL计算程序,以我国高铁第一座钢箱叠合拱桥哈大高速铁路新开河特大桥为工程背景,计算分析了该桥梁端转角的可靠度.结果表明该桥的转角可靠度符合要求.
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.
