Experimental investigation was conducted to characterize the responses of Strain-Hardening Cementitious Composites (SHCC) when subjected to triaxial and compression. The SHCC examined in this test is a class of fiber reinforced cementitious composites with ultra-high ductility by using a low volume fraction (2%) of Polyvinyl Alcohol (PVA) fiber. One kind of SHCC was examined with cubic specimen size of 100mm in the tests. The specimens were loaded with a servo-hydraulic jack at different stress ratios. The principle stresses and strains of the specimens were recorded, and the failure modes with various stress states were examined. The experimental results indicated that the stress states and stress ratios had significant influence on the strength and deformation of SHCC under triaxial compression. The failure mode showed a shear-type failure because of bridging effect of fibers. The test results provide a valuable reference for obtaining multi-axial constitutive law of SHCC.
