Abstrakt: Summary The paper describes the construction and operation of an hydraulically operated fatigue machine of 5 tons capacity for tests in bending or compression. The machine proved capable of long periods of service with the minimum of attention. A series of fatigue tests in bending on normally reinforced concrete beams indicated that high proportions of the static failing load could be applied as many as 300,000 times without significantly altering the ultimate strength of the beams.
