Controlling Closure of Steel Arch by Unstressed Cable Length |
| |
| Abstract: | Today,Controlling cable force by the unstressed cable length is widely used in cable-stayed bridge girder cable force monitoring method.For the tied arch bridge in this article,we solved the troubles of determining how much cable force in integral lifting the overall arch conveniently,by the method of above. |
