Abstract
An experimental investigation is presented, the principal object of which was to determine which portion of the ultimate strength under fast (short-time) loading an eccentrically loaded reinforced concrete column can sustain indefinitely. Forty-five column tests are reported; 13 tests were made with fast loading, 12 with slow loading, and 19 with sustained loading. In addition to the type of loading, concrete strength and eccentricity of load were the major variables studied. The test findings indicate that the ultimate strength under sustained loading is only about 10 percent below that for fast loading. It seems satisfactory, therefore, to base safety in ultimate strength design on the ultimate strength equations for fast static loading, which equations are substantiated by numerous previous tests.
