Spatial finite element analysis for Weiping Bridge and its static loading test

The finite element program ANSYS is adopted for spatial analysis of concrete-filled steel tube skeleton arch bridge. The static loading test of the bridge is introduced in the paper, and the measured and calculated results are compared. It represents that the method of controlling equivalent inner force in section for test is easy and accurate; the deformation is conformed with assumed value in balance section after applying force to an arch rib section of reinforced concrete;secondary distributed inner force to cross bar of Weiping Bridge is weak in eccentric loading.
