| Abstract | ||
| This paper presents an investigation for the behavior of foam filled circular steel tubes under static axial loads through numerical and experimental test program. Six specimens were included in the experimental test program divided into three groups. The tubes were of different diameters, wall thickness and different lengths. One tube of each group was filled with Polyurethane (PU) foam with density of 30 kg/m3 . All specimens were exposed to axial compression using compression test machine. Numerical simulation was also conducted and the results showed good agreement with experimental tests. Results conclude that there was no effect in the load carrying capacity by using lower foam density filling steel column, but there was an increase in the load carrying capacity by using construction foam (metallic foam). The results also showed noticeable reduction in local buckling phenomenon besides a more ductile behavior for this type of elements. | ||
