Abstract

Nine specimens were tested to investigate the local bearing capacity of steel beams with corrugated webs. Then, the influence of different load distribution widths on local bearing capacity was studied. Results showed that the failure modes of the specimens were web yielding and changed from brittle failure to plastic failure at increased distribution width. The ultimate bearing capacities were higher than those of steel beams with plate webs. Meanwhile, the loading course, ultimate load and failure modes were closely simulated through the finite element method, and parameter analysis was performed, the result of which verified the decreased capacity of the sparse waveforms. The design expression of the local bearing capacity under different load distribution widths were obtained on the basis of these results and applied to crane beams with corrugated webs. The calculated results compared with finite element analysis and experimental results suggested the correctness and reliability of the design expression.
