Mechanical Mechanism Analysis of Longitudinal Cracks Appeared in a Large Cable-stayed Bridge Cable Tower
The cable-stayed bridge which has been found longitudinal cracks in tower is taken as the background, combining with the original design information and the results of bridge inspection.The numerical simulation on temperature effect of cable tower has been done with MIDAS/Civil, and the results have the same trend with observed in bridge inspection, indicating that the cracks in tower probably are caused by temperature effect.Then, some suggestions are raised in the end of this paper about how to deal with these cracks.This work could be a valuable reference for similar large cable-stayed bridge.And the temperature stress should be paid more attention in design process to avoid appearance of temperature cracks which affect beauty and durability of structure.
