Description:
In order to investigate the buckling performance of castellated beams, three hexagon-hole castellated beams with different depth-thickness ratio and stiffeners setting were tested under pure bending. By observing and comparing the failure mode and the relationship of moment-curvature, the local stability and overall performance of beam webs were studied. The experimental results show that under pure bending, the buckling mainly occurs in the bridge plate above the openings and pier plate among the openings. Reducing the depth-thickness ratio of the web and setting stiffeners can improve the web buckling performance and the overall performance of castellated beam.
