| This paper is one part of the "Research on the Traction System and Catwalk of Suspension Bridge", which presents research on the structural parameter design and static analysis of the catwalk as listed below.1.The detailed structural parameters of catwalk are discussed and their according factors which should be considered when design are introduced, what's more, the erection method and process for the construction of catwalk and its advertent proceedings are explained thoroughly.2. During the calculation of catwalk, the analytic method is introduced to fulfill the calculation of unstressed cable length. line sharpx internal force and height mark.3. To the design and strength checking computations for bearing rope of catwalk, the consideration of designing load. load selection and load combination are analyzed, which provide some theoretical reference to technicians when designing and calculating catwalk.4. With the method put forward in the paper, the calculation program is given using Excel and VBAas flatform, which can calculate the bearing rope length. baiting length. internal force and height mark of control point. At last, the paper presents Wanzhou Bridge as the calculation example and checks the calculation method and program of this paper. |
