- Abstract:
- In view of the at characteristic that the cable shape is very sensitive on the temperature in theprocess of main cable erection．Influence of the temperature changes on main cable section and bridge tower tothe cable shape was researched．According to invariable temperature models of the cable，correction methods oftemperature changes leading to sagging variation under the unloaded cable condition were proposed based onlength of non—stress wire strand is equal，and computational method about temperature changes of bridge towersection to give rise to cable sag variable values was given．Sagging values with methods of iteration are in agreement with the results of finite element program SBCC in different temperature conditions，and the maximum deviation value is 9 mm and is about 3％．It shows that the correction methods on temperature changesleading to sagging variation are feasible to adjust suspended cable shape．
