| Summary: | Shear buckling occurred in the instability modes of steel beams when it slender. This paper developsa three-dimensional finite element model using LUSAS 14.3 to study on the effect ofthe triangularsteel beamwebprofile (T WP) inshearbuckling behaviourof differentthicknesscompared RI to that of thenormalflatbeam (FW).All specimens are cantilever beam which are fixedat one ends. The flange is constant with variable webthickness. Eigenvalue buckling analysis was used in analysing the buckling load of the flat plate model andtriangular web profile (TRIWP). Results showed that the web thickness gave a significant impact on the shearbuckling of the TRIWP. In addition, the corrugation thickness of web was also effective in increasing the shearbuckling capacity of the profile. |
