Research On Hanger Tension Optimization For Self-anchored Suspension Bridge

Against the feature of self-anchored suspension bridge, the hanger have to be tensioned, based on theprevious optimization theories such as minimum bending energy principle, inteinal force equilibriummethod, influence matrix method, this dissertation do the simplified analysis of self-anchored suspensionbridge, deducing the simplified analysis method of hanger tension in dead load stage. Then base on theweak interference of cable displacement and near influence of hanger tension theories, deducing thesimplified computation method in construction stage. Accouding to the result from optimization, contractwith the result that from using the finite element sofeware ANSYS, we consider the geometric nonlinearand so on. Through the example proving, deduce the simplified optimization method which iseffectiveness, and disproof the weak interference of cable displacement and near influence of hangertension theories is illogicality.At last, analyzing the tension orde and tension scale individual and proving in the engineeringexamples, this dissertation gets the tension program which is valuable. Making use of the theory result, thisdissertation present some problems need to be paid attention to and suggest some conclusions and advicethat is valuable. Base on the computation result, it disproof the limitation of weak interference of cabledisplacement and near influence of hanger tension...
