Axial Loading Tests on Short Reinforced Lightweight-Aggregate (Lytag) Concrete Columns

The paper describes tests on twenty-seven Lytag concrete columns. Sixteen of the columns were reinforced with varying percentages of square twisted steel and the remaining eleven were unreinforced. It was found that, although the ultimate loads of reinforced Lytag concrete columns are slightly less than those of equivalent gravel concrete columns, the load factors are satisfactory. It is therefore safe to design reinforced Lytag concrete columns with the permissible stresses specified in CP l14 (1957). C.O. Orangun
