The influence of factors such as the ratio of bearing area under the square plate and the eccentricity on the stress properties of the high strength concrete specimens is studied. According to the wedge model and the principle of limit equilibrium, a theoretical calculation formula is derived and a practical calculation formula is established. For eccentric compression, the linear relationship between the eccentricity and the coefficient of increase of the compressive strength βc and the value of Ad are determined based on the test results.
