The main contents about calculation of cable curve for suspension bridges are as follows : firstly, parabola theory, a traditional calculation theory of linetype for suspension bridge, is introduced. according to behavior of suspension bridge, segmental catenary theory which is an exact calculation theory of cable curve for suspension bridges is then built. after that, the errors and adaptable range of segmental parabola theory, segmental straight - line theory and traditional parabola theory are compared one another
