Peak strength, mechanical behavior, and pattern of shear band (SB) of anisotropic jointed rock specimen were modeled by FLAC. The failure criterion of intact rock was a composite Mohr-Coulomb criterion with tension cut-off and the post-peak constitutive relation was linear strain-softening. Joint was treated as quadrate elements of ideal plastic material beyond peak strength. Intact rock without joint has a higher peak strength. Shear strain of jointed rock is concentrated into joint or new generated SBs. Peak strength of jointed rock depends on the joint inclination (JI). The new SBs are origanated from the two ends of joint and propagate along their inherent directions. For moderate JI, lower strength and the behavior of jointed rock specimen are mainly governed by joint. For lower or higher JI, the peak strength of jointed rock specimen is higher and the strain softening behavior is apparent. For lower JI, slip along SB has a greater contribution to the axial strain of jointed rock, leading to steeper post peak stress strain curve. For higher JI, the slope of post-peak stress-strain curve is not dependent on JI since JI does not influence the thickness and the inclination of SB.
