Resumo:
Sustained loads cause a progressive increase of the strains in a structure due to concrete creep. In general, creep strains do not affect the strength of the structural elements. In slender columns, however, they can reduce the load capacity as a result of the continuous increase of the second order eccentricity, leading to the column instability. An experimental investigation on the effects of concrete creep on the behavior of slender columns was carried out in the present study. Six columns 210 cm long, with cross sections of 12,5 cm x 15 cm, were tested subjected to sustained eccentric compressive loading. The main objective was to study the effect of the increase of the second order eccentricity on the ultimate strength of the columns. The experimental results were compared with results obtained from theoretical methods available in the literature .
