    Abstract

    The response to random loading of short reinforced laterized concrete columns was investigated by testing, under three cycles of loading and unloading, three columns cast from 1:2:4, 1:1½:3, and 1:1:2 mixes by weight and reinforced with four 12.7-mm (½-in.) diameter mild steel rods. The results obtained from the test showed that randomly loaded columns are capable of withstanding higher compressive stresses (80 to 95% cube strength) before failure than similar columns loaded to failure in one cycle. An attempt was made to discuss the inherent differences between the transformed section theory assumed for an “elastic” concrete component of a composite column and the theory applicable to a “viscoelastic” concrete, which laterized concrete approximates.
