摘要
依据试验结果，对Ｏｔｏｓｅｎ模型参数作适合于高强混凝土的修正，把Ｏｔｔｏｓｅｎ理论延伸到处于压剪应力状态的高强混凝土，并验证了它的适用性．
The Ottosen failure criterion for concrete under triaxial stresses has been accepted by CEB-FIP Mc 90.Based on the author s test results,the Ottosen parameters are revised as regards to the difference between expressions for mechanical indexes of concrete. It is true that the Ottosen failure criterion is also suitable for high-strength concrete under combined compressive and shear stresses.
