Shear Behavior of Corrugated Steel Webs in H Shape Bridge Girders

Table 3

Failure mode classification.

Mode	Description of failure
A	One fold plate of webs was buckled first. As load increased, the buckling line appeared along 60° at upper left corner or bottom right corner, resulting in buckling of adjacent fold plate.
B	One fold plate of webs close to top flange was buckled first and then it approached to middle stiffener. As load increased, buckling was developed to flanges longitudinally. Finally the area between flange and webs buckled.
C	Web was buckled along the diagonal direction between two adjacent stiffeners and then both sides of the specimens buckled continuously.
