Research on the Influence of Environmental Temperature on Cable Force of Cable-stayed Bridges
This study used the finite element software Midas Civil to construct a detailed model of a single tower double cable plane cable-stayed bridge.Taking the Suotongpo Yellow River Extra-large Bridge as a case study,the changes in cable force of the cable-stayed bridge under environmental temperature changes are explored.Through simulation analysis,it can be concluded that as the temperature increases,the cable force of the inclined cable will also decrease;on the contrary,a decrease in temperature will increase the cable force.This discovery provides a scientific basis for the design and construction of cable-stayed bridges,especially in considering temperature effects.In addition,the study emphasizes the importance of temperature monitoring in maintaining the safety of cable-stayed bridge structures,and suggests strengthening real-time monitoring of environmental temperature changes in bridge management,to prevent potential structural problems caused by temperature changes.This study not only deepens the understanding of temperature sensitivity of cable-stayed bridges,but also provides important reference materials and practical guidance for the field of bridge engineering.
