Abstract:
Tests on steel columns filled with normal concrete and lightweight concrete were carried out to investigate
the actual behavior and the load carrying capacity of such columns. Eight full scale rectangular cross-section
columns filled with lightweight aggregate concrete and normal weight aggregate concrete, four specimens
each, were tested under axial loads for comparison purposes. The results showed that using lightweight
concrete filling instead of normal concrete filling will reduce the weight of columns. At the same time, a high
load carrying capacity is achieved.
