Strain is an important parameter measured to understand the stiffness characteristics of soil structure. Stress-strain graph obtained from triaxial compression test is widely being used as one of the precise method to measure the shear strength of soil. Soil is known for its poor tensile strength and derives it compressive strength mainly from its shear strength. Hence, the shear strength of soil is employed in designing the foundation of all the civil engineering structures, stability analysis of slopes, designing earth retaining walls, embankments and man-made excavation etc. The soil failures like landslides, differential settlement and earthquake induced liquefaction etc., causes dislocation and considerable changes in the strain. During laboratory triaxial compression test, some of the samples has shown strain hardening behavior (continuous taking load without fail). To understand the importance of strain when peak stress has not reached, two different failure strain conditions (i.e., 15 % and 20 %) were assumed for analysis. Shear strength parameters for both the failure conditions are evaluated and reported in this study.
