| Abstract: | A deck type bridge constructed with reinforced concrete has different arch axes between design and actual construction.The effects of deformation and internal forces produced by transverse bias of arch axis are analyzed by simulative computing.Several measures used to improve the statements of main box-ribbed arch under loading are presented.These methods could be used as a reference to improve,repair and strengthen the similar arch bridges having initial bias arch ring in future. |
