Load bearing capacity of thin-walled rectangular and I-shaped steel sections of short both empty and concrete-filled columns
In this experimental work, strength results obtained on short columns subjected to concentric loads are presented. The specimens used in the tests have been made of cold-rolled, thin-walled steel. Twenty short columns of the same cross-section area and wall thickness have been tested as follows: 8 e...

| description | In this experimental work, strength results obtained on short columns subjected to concentric loads are presented. The specimens used in the tests have been made of cold-rolled, thin-walled steel. Twenty short columns of the same cross-section area and wall thickness have been tested as follows: 8 empty and 12 filled with ordinary concrete. In order to determine the column section geometry with the highest resistance, three different types of cross-sections have been compared: rectangular, I-shaped unreinforced and, reinforced with 100 mm spaced transversal links. The parameters studied are the specimen height and the cross-sectional steel geometry. The registered experimental results have been compared to the ultimate loads intended by�Eurocode�3, for empty columns, and by�Eurocode�4, for compound columns. These results showed that a concrete-filled composite column had improved strength compared to the empty case. Among the three cross-section types, it has been found that I-section reinforced is more resistant than the other two sections. Moreover, the load capacity and mode of failure have been influenced by the height of the column. Also, the EC3 and EC4 predictions were not conservative compared to the experimental strengths of the tested columns |
