Abstract:The principal object of this experimental investigation was to determine which portion of the ultimate strength under fast (short-time) loading can be sustained indefinitely by an eccentrically loaded reinforced concrete column. 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.
