| Abstract: | In terms of the determining principles,influential factors and determining methods of the reasonable finished dead state of the concrete cable-stayed bridges,a comprehensive method is developed.The procedure of this method is: deciding the initial dead state by using the minimum bending energy method firstly;then optimizing the cable forces by using the influence matrix method.And finally the reasonable finished dead state is determined.This method is used to calculate an actual bridge,and the result of the... |
