Experimental Buckling Loads of Water‐Loaded Beams

Abstract

This note reports results of two tests performed on full-scale thin-walled prestressed concrete beams where the increase in external load is caused by changing the water level contained in the beam section. The purpose of the experiments was to contrast experimental values of the buckling load with predictions based on a numerical model of the problem, which had anticipated a buckling load significantly lower than the classical lateral torsional buckling load associated with solid-type loading. Experimental results confirm the validity of the theoretical model.
