Study of Buckling Behaviour of Beam and Column Subjected To Axial Loading for Various Rolled I Sections

Rekha Bhoi , L. G. Kalurkar

In this paper the buckling behaviour of an I - beam under axial load on column and beam is examined. Buckling loads are critical loads where certain types of structure become unstable. The results of an extensive parametric study are presented in graphical form and summarized by simple design curves and ev aluating the effect of critical buckling load for various symmetrical rolled I - sections like Indian Standard Junior Beam (ISJB), Indian Standard Light Weight Beam (ISLB), Indian Standard Medium Weight Beam (ISMB), Indian Standard Wide Flange Beam (ISWB), Indian Standard Heavy Weight Beam (ISHB) for different depth are calculated by using software Ansys. The results of critical buckling load calculated using Ansys are compared with the conventional method of Euler Buckling theory analytically.
