A study of the failure of concrete under combined compressive stresses

The investigation has been carried out in two parts: (1) a study of concrete specimens loaded in compression in one, in two, or in three directions at right angles to each other by means of fluid pressures, and (2) a study of plain and spirally reinforced concrete compression specimens loaded in one direction in the usual manner. The bulletin contains the results of the first group of tests (series nos. 2, 3A, and 3B) ... It is planned to report the second group of tests (series no. 1) in a later bulletin [i.e. Bulletin no. 190].
