Abstract: The paper is focused on the study of the influence of the factors such as the bearing area ratio. and its eccent ricity on the local bearing strength of high-strength concrete. Using the theoretical formula derived as reference, the equations for practical computation are established. A linear relationship between the eccetricity ei and the local bearing strength factor β as well as the simplified method calculation Ad are determined for the case of eccetric load.
