Experimental Analysis of Post-Buckling and Collapse Behaviour of Thin-Walled Box-Section Beam

摘要

This paper contains the results and analysis of tests carried out on a large-scale model of the thin-walled box-section beam subject to pure bending. The whole range of loading was analysed— up to the collapse of the beam. The stress and deflection distribution in selected beam cross-sections is presented by means of diagrams. The magnitudes of buckling load and ultimate load obtained on the basis of the tests results are compared with the results of the theoretical analysis.
