| Abstract: | Mechanical performance,such as load bearing mechanism,mechanical characters,damage form and ultimate load capacity of steel block deviator used in externally prestressed box girder with corrugated webs was studied using FEA(finite element analysis) and experimental methods.In FEA,local influence of girder caused by deviator was studied in the whole beam model;mechanical behaviors of deviator from loading to damage were studied in the local deviator model.Experiment was conducted to verify the FEA results an... |
