The sensitivity analysis of structural design parameters for Guanyinyan Yangtze River Bridge in Jiangjin

Based on the Guanyinyan Yangtze River Bridge of Jiangjin,and through the use of finite element analysis program-BSAS4.24,we calculated and compared the impact of various design parameters in the girder line,the girder stress,in addition,analyzed the sensitivity of the design parameters.We concluded that the main beam weight,the length of cable manufactured,the weight of the bridge deck all have a significant influence while the stiffness of the bridge deck and the main beam bridge have not prominent influence,and accordingly put forward the views of the monitor.
