N2 - The sinusoidal types of cyclic loading have been commonly used for investingating dyamic responses of soils under earthquake loading, primarily due to simplicity. In this study, dynamic triaxial tests with different types of dynamic loadings including sinusoidal, triangular, incremental, and 9 real earthquake loadings were performed to investigate effects of loading type on liquefaction behavior. Based on test results, mobilization of the excess pore water pressure and the deviatoric stress is analyzed and compared. The phase transformation line from the effective stress path is introduced and investigated for generation of initial liquefaction. Stress damage concept based on the stress-time history and the cumulative energy is addressed and investigated as well.
