Abstract: Calculation of zero-stress length of main cable is the effective guarantee for construction control of suspension bridge superstructure. Common software Midas /Civil was used to build finite element model for Fuling Qingcaobei Yangtze River Bridge to correct zero-stress length of cable strand for suspension bridge. The general methods of adopting common software to build model of suspension bridge and of calculating the zero-stress length of main cable were put forward to provide reference for this kind of calculation.

Key words: suspension bridge, zero-stress length of main cable, Midas /Civil, length correction
